This package offers basic LDAP services for Foswiki and offers authentication of wiki users by binding to an LDAP server as well as incorporate LDAP user groups into access control.

Optionally, if you need an interface to query your LDAP directory and display the results in a topic install the LdapNgPlugin which will make use of the LdapContrib services. This work is a rewrite of the LdapPlugin by Gerard Hickey while bringing authentication, user management and other LDAP applications onto a common base.

This package downloads all relevant records from your LDAP server into a local cache the first time you use it. This can take a noticeable period of time depending on the size of your LDAP database. This cache will be refreshed on a configurable interval (defaults to once a day). You can also disable automatic refreshing and refresh the LdapContrib's cache manually using the "Refresh Cache" button below. Read the documentation of MaxCacheAge in the section "Performance Settings" in configure.

Refresh Cache

Tip: You can add this button on any page by adding

%INCLUDE{"%SYSTEMWEB%.LdapContrib" section="refreshbutton"}%

to it.

LDAP questionnaire

Before you can further configure the LDAP connection you will have to answer a set of basic questions about your LDAP server. These are:

  1. What's the host name (or IP address) of the LDAP server (e.g. ldap.my.domain.com)?
  2. What port does it listen to LDAP requests (e.g. 389)?
  3. Does your LDAP Server use SASL to authenticate connections? If so which authentication mechanism does it use (EXTERNAL, DIGEST-MD5, ...)?
  4. Do you have a kind of "proxy" user that the wiki can use to perform the initial connection? You need its DN and credentials. Advice: don't use the LDAP admin account, you only need a simple user that has read access to all of the directory (or the relevant parts); it does not need any write access.
  5. What is the "base dn" of the directory (e.g. dc=my,dc=domain,dc=com )?
  6. What is the common root/branch for all users? For example, Are they all found under ou=people,dc=my,dc=domain,dc=com or are they are scattered all over the place?
  7. What is the common root/branch where all groups are defined (e.g. ou=group,dc=my,dc=domain,dc=com)?
  8. What object class do user records have (e.g. objectClass=organizationalPerson )?
  9. What object class do group records have (e.g. objectClass=group )?
  10. Which attribute of a user record should be used to log in (must be unique)?
  11. Which attribute(s) of a user record do you want to use to construct a WikiName (used to display them online, pointing to their homepage)?
  12. What attribute of a user record holds the email address?
  13. What's the name attribute of a group?
  14. Which attribute in a group record defines its members (e.g. member or memberUid)? Note, that if the member attribute of a group is a DN you need to enable "member indirection" (see #Membership).

Collect the answers to these questions either yourself using your favorite LDAP browser, or ask your friendly LDAP admin.


To authenticate wiki users using your LDAP server you have to register the LdapPasswdUser class as the so called PasswordManager. This is done by adding the following lines in the lib/LocalSite.cfg configuration file (or by using the configure tool alternatively):

$Foswiki::cfg{PasswordManager} = 'Foswiki::Users::LdapPasswdUser';

There is a further option to fallback to the normal authentication mechanism by defining a secondary password manager. This allows you to create native wiki accounts, e.g. a WikiAdmin account and authenticate him without LDAP. Use the following setting to fallback to a htpasswd based authentication.

$Foswiki::cfg{Ldap}{SecondaryPasswordManager} = 'Foswiki::Users::HtPasswdUser';

So whenever authentication against LDAP fails, this second password manager will be used.

User Groups

LDAP group records can be used in access control lists by registering a UserMappingManager implementation. This is done by adding the following to your lib/LocalSite.cfg configuration file (or by using the configure tool alternatively):

$Foswiki::cfg{UserMappingManager} = 'Foswiki::Users::LdapUserMapping';

In addition you can decide if you want to add the LDAP groups or use LDAP groups solely. This is controlled by the WikiGroupsBackoff flag. If switched on then LDAP groups will be added. If there's a name clash LDAP groups take precedence. If switched off WikiGroups are ignored.

You might decide in not using your LDAP groups but still map login names to WikiNames. Both, LDAP user groups and name mapping is done by the UserMappingManager. So to make use of name mapping but not its group feature, register the LdapUserMapping implementation for the UserMappingManager but disable the MapGroups setting.

When multiple groups in your LDAP directory clash on the same group name you might actually wish to merge these groups as used online in your wiki. This is done using the MergeGroups flag. When disabled, clashing groups are reported as a warning in the server log files when the LDAP cache is refreshed.


LDAP servers follow different schemata to define "membership". They store the information either using a set of unique ids in the group object (posixGroup) or the full DNs of the user objects (groupOfNames). In the latter case the user objects' unique ids have to be fetched separately based on their distinguished name. This mode has to be switched on using the MemberIndirection setting.

The reverse relation, where the user objects hold membership information (for example using a memberOf attribute) is maintained by some LDAP servers automatically. Those that encode membership this way only are not supported by the LdapContrib yet.

Furthermore, user objects may have one primary group attribute. This is a simple value that stores the id of a default group that user is member of. This attribute is defined by specifying the PrimaryGroupAttribute setting a.

LdapContrib reads membership information as they are stored in the group objects, and may map the member object indirectly to the login name. In addition any "primary group" setting stored in the user objects is consulted as well.

Normalization of login, wiki and group names

LdapContrib reads three kinds of names from your LDAP server and reuses this information as needed. These are the login names - used to log in -, the WikiNames - used to display users online -, and the group names - used in access control lists.

The WikiName can be generated by setting the parameters

  • WikiNameAttributes: a comma sedparated list of LDAP attributes taht are then assembled to form a proper WikiName
  • NormalizeWikiName: boolean flag; if set a couple of extra operations are performed to generate a proper WikiName, i.e. removing illegal characters.
  • WikiNameAliases: a comma separated key=value list of WikiNames to be mapped to another WikiName (DEPRECATED: use RewriteWikiNames instead).
  • RewriteWikiNames: a list of rewrite rules; see below
  • UserMappingTopic: a topic that holds a pre-defined login-to-wikiname mapping; this comes in handy when migrating from a TopicUserMapping to an LDAP setup where names already in use should be preserved. Note that no rewrite or normalization is applied if a login name is found in the database

Given the setting

$Foswiki::cfg{Ldap}{WikiNameAttributes} = 'givenName,sn';
$Foswiki::cfg{Ldap}{NormalizeWikiNames} = 1;

The givenName and sn (surname) LDAP attributes will be fetched and concatenated to form a proper WikiName, so that "givenName=Hans-Peter,sn=Schwarze" will result in the WikiName "HansPeterSchwarze".

The login name can be normalized by enabling the

$Foswiki::cfg{Ldap}{NormalizeLoginNames} = 1;

setting. This will also strip off any '@...' string from the login as found when logging ing using the mail attribute or when using LdapContrib in combination with a kerberos single sign on strategy.

In most scenarios users prefer not to care about case sensitivity of their login names for convenience. If however your authentication requires an exact match of the login name including case sensitivity, the use

$Foswiki::cfg{Ldap}{CaseSensitiveLogin} = 1;

to switch that on.

Similar to the WikiName of a user, group names can be normalized using

$Foswiki::cfg{Ldap}{NormalizeGroupNames} = 1;

If a user in your LDAP directory changed his name, e.g. because of a marriage, this use can be mapped to his/her old account using an alias that points back from the old WikiName to the new one. This is done using a setting like this:

$Foswiki::cfg{Ldap}{WikiNameAliases} = 'MaryMalone=MaryForrester, ...'

The parameter takes a comma separated list of FromWikiName=ToWikiName. Whenever this account is still used in an access control list, its rights will be inherited by the targeted ToWikiName account.

Group names can be rewritten using a set of rewrite rules. This is useful when the names as stored in your LDAP directory don't satisfy your criteria for being displayed online. In conjunction with the MergeGroups flag, separate LDAP groups can be merged onto one group as it is used online in your wiki.

A group rewrite rule is specified using

$Foswiki::cfg{Ldap}{RewriteGroups} = {
  'pattern1' => 'substitution1',
  'pattern2' => 'substitution2',

Each rule consists of a pattern that will be substituted in the group name as specified. The substitute can contain variables $1, $2, ... , $5 to insert the first, second, ..., fifth bracket pair in the key pattern. (see perl manual for regular expressions).


$Foswiki::cfg{Ldap}{RewriteGroups} = {
  '(.*)_users' => '$1'

WikiNames can be processed similarly using the $Foswiki::cfg{Ldap}{RewriteWikiNames} parameter. Given the WikiName is derived from the mail attribute, then use the following rule to strip off domain parts from the wiki name:

$Foswiki::cfg{Ldap}{RewriteWikiNames} = {
  '^(.*)@.*$' => '$1'

This can be further refined to prevent name clashes by adding back the domain part:

$Foswiki::cfg{Ldap}{RewriteWikiNames} = {
  '^(.*)@(.*?)\..*\..*$' => '$1_$2'

So given your company uses email addresses like john.doe@germany.mycompany.com and john.doe@spain.mycompany.com it will generate the wiki names JohnDoeGermany and JohnDoeSpain from it (given NormalizeWikiNames is switched on too).

Another trick is to add additional LDAP attributes to the WikiNameAttributes that help to create unique WikiNames, and then strip off unwanted parts again with an appropriate rewrite rule.


$Foswiki::cfg{Ldap}{WikiNameAttributes} = 'givenName, sn, sAMAccountName';
$Foswiki::cfg{Ldap}{RewriteWikiNames} = {
  '^(.*) [^ ]+?\-adm$' => '$1 Admin',
  '^(.*) (?!\-adm$)[^ ]+?$' => '$1',

This might look wild at first but does the following:

  • generate a temporary WikiName concatenating the attributes according to the WikiNameAttributes setting, e.g. "John-Doe Smith jds", where jds is the sAMAccountName value
  • let's say there's also a second record for John-Doe Smith that he uses to log in
  • with admin rights using his jds-adm login.
  • rule 1 of the RewriteWikiNames will match the jds-adm and will generate a nice John-Doe Smith Admin, whereas
  • rule 2 will only match those records that don't have the -adm suffic at their sAMAccountName.
  • note that both rules only copy over the first part of the string captured in brackets (.*) over to the result leaving out the trailing sAMAccountName part.
  • finally the string is wikified to make it a proper CamelCase word by all non-alphabetic characters between the parts of the name

WikiName clashes

Depending on the choice of WikiNameAttributes and RewriteWikiNames rules your LDAP records will be mapped onto a proper WikiName. These have to be unique to represent the identity of the person granted access to Foswiki. However, while you LDAP records are unique due to their Distinguished Names, it is quite common that two independent records result in the same WikiName. That's a so called name clash. You are strongly encouraged to control the way WikiNames are generated to keep the number of name clashes as low as possible. Use appropriate rewrite rues as described above.

In real world you will most probalby run into a name clash that you can't possibly resolve. In that case LdapContrib will enumerate all JohnSmiths as they are found, calling them JohnSmith, JohnSmith1, JohnSmith2, etc. Each of these maps back to a unique Distinguished Name in your LDAP directory of course.

LdapContrib tries to keep the choice which of the JohnSmiths maps to which DN stable over time. Whenever you refresh the LDAP cache the previous WikiNames will be reused while new LDAP records will get a higher number attached to the WikiName.

When LdapContrib is building up its cache for the first time, the actual mapping is pretty arbitrary, given there are no additional means to distinguish the names. From there on WikiNames are kept, even when you reconfigure LdapContrib itself. This is the default behavior not to risk mapping a different identity to a WikiName.

You still might decide to nuke the decisions once made while resolving name clashes by refreshing the ldap cache using the refreshldap=force url parameter (compared to refreshldap=on to up the cache regularly).

ALERT! Note doing this later in the life time of your wiki might accidentally swap the mapping of LDAP records to WikiNames in case they clash. So be very cautious when doing that.

Single Sign On and LdapContrib

ALERT! Note that the KerberosLogin manager depends on CPAN:GSSAPI and requires Foswiki >= 2.0.0

LdapContrib might be used as an out-of-the-box SSO solution. The only other prerequisite is that you need to integrate the HTTP server into the LDAP domain. A keytab for the HTTP service must be generated and placed in a secure location readable by the Foswiki server. The path to this keytab file must be configured in {Ldap}{KerberosKeyTab} (defaults to /etc/krb5.keytab). The LoginManager must be set to KerberosLogin. Foswiki will then initiate the negotiation process with the user's browser so that it submits an authentication token on the base of the user's kerberos ticket. The authentication token will then be used to derive the login name of the user automatically.

LdapContrib is then used to complete an LDAP integration by mapping the login name to the WikiName, email information and group membership gathered from the LDAP directory directly.

Note that the negotioation process will only be initiated either on access-restricted resources, or by visiting the Login url.

When no valid kerberos ticket is available on the client side will the authentication fall back to a template based login to enter credentials manually as if the TemplateLogin LoginManager has been used.

Simple Example

For the sake of this documentation we assume that users accounts in your database are at least of the type posixAccount and optionally also of type inetOrgPerson storing email addresses. Moreover users are stored in a subtree ou=people and groups are defined in ou=group. Here are some example LDAP records:

dn: uid=testuser1,ou=people,dc=my,dc=domain,dc=com
objectClass: inetOrgPerson
objectClass: posixAccount
cn: Test User1
uid: testuser1
uidNumber: 1024
gidNumber: 100
homeDirectory: /home/testuser1
loginShell: /bin/bash
mail: testuser1@my.domain.com

dn: uid=testuser2,ou=people,dc=my,dc=domain,dc=com
objectClass: inetOrgPerson
objectClass: posixAccount
cn: Test User2
uid: testuser2
uidNumber: 1024
gidNumber: 100
homeDirectory: /home/testuser2
loginShell: /bin/bash
mail: testuser2@my.domain.com
mail: testuser2@gmx.com

# users, Group, nats.informatik.uni-hamburg.de
dn: cn=users,ou=group,dc=my,dc=domain,dc=com
objectClass: posixGroup
cn: users
gidNumber: 100
memberUid: testuser1
memberUid: testuser2

Please have a look at your LDAP manual on how to set up an LDAP server and populate it with user account records. Have a look at the Quick-Start Guide on how to install OpenLdap.

Use the following settings for the above example:

$Foswiki::cfg{Ldap}{Host} = 'ldap.my.domain.com';
$Foswiki::cfg{Ldap}{Port} = 389; 
$Foswiki::cfg{Ldap}{UserBase} = ['ou=people,dc=my,dc=domain,dc=com']; 
$Foswiki::cfg{Ldap}{LoginFilter} = 'objectClass=posixAccount';
$Foswiki::cfg{Ldap}{LoginAttribute} = 'uid';
$Foswiki::cfg{Ldap}{WikiNameAttributes} = 'cn';
$Foswiki::cfg{Ldap}{NormalizeWikiNames} = 1; 
$Foswiki::cfg{Ldap}{GroupBase} = ['ou=group,dc=my,dc=domain,dc=com'];
$Foswiki::cfg{Ldap}{GroupFilter} = 'objectClass=posixGroup';
$Foswiki::cfg{Ldap}{GroupAttribute} = 'cn';
$Foswiki::cfg{Ldap}{MemberAttribute} = 'memberUid';
$Foswiki::cfg{Ldap}{MemberIndirection} = 0;
$Foswiki::cfg{Ldap}{MapGroups} = 1;


$Foswiki::cfg{Ldap}{Host} = 'ldaps://ldap.my.domain.com';
$Foswiki::cfg{Ldap}{Port} = 636;
$Foswiki::cfg{Ldap}{TLSCAPath} = '/etc/openldap/cacerts/';
$Foswiki::cfg{Ldap}{TLSCAFile} = 'cer.pem';
$Foswiki::cfg{Ldap}{TLSClientCert} = 'cer.pem';
$Foswiki::cfg{Ldap}{TLSClientKey} = 'cer.key';


The LdapContrib package is configured using a set of variables that need to be added to the lib/LocalSite.cfg configuration file. Use the configure tool (at least once) after you installed this package. Have a look at your lib/LocalSite.cfg file afterwards. You might also make your changes therein directly to accommodate your installation to your specific LDAP installation and user accounting. See the documentation within the configure tool for an explanation of the various options.

Updating the LDAP cache using a cronjob

In some environments, updating the internal LDAP cache of the LdapContrib might take considerable time. The intervals the cache data is thought to be "expired" is configured using the MaxCacheAge setting. This setting defaults to updating the cache every 24 hours. The refresh procedure will then be triggered by the first request that hits the site when this period expired.

To remove this burden from the "first visitor in the morning", the automatic refresh procedure can be disabled by setting

$Foswiki::cfg{Ldap}{MaxCacheAge} = 0; 

This means that the age of the cached data will not be checked automatically anymore. The responsibility that the data is updated is now up to you, that is you have to update the cache explicitly. This can be done by either hitting the red "Refresh Cache" button above, or by setting up an appropriate cronjob on the machine running your wiki server.

To trigger an explicit update of the cache on 5 past midnight every day use a cronjob similar to:

5 0 * * * cd <wiki-install-path>/bin && ./view refreshldap=on Main/WebHome >/dev/null

This will call the engine on the command line and provide the necessary query parameters so that the LdapContrib will force an update of the cache data.

Debugging LDAP

Very often either the directory structure of your LDAP server is rather complicated or the settings of LdapContrib are not as intuitive or easy to comprehend. For this reason the first best thing to do is to enable {Ldap}{Debug} in configure and analyze the output as generated in the error.log file of your web server. Try to examine the output as generated by (a) a normal access to the site versus (b) a refresh of the LDAP cache. There should be sufficient information in the log files to get to know what exactly happens during this imporant step.

Note that that {Ldap}{Debug} will only switch on debug notes of LdapContrib, not of your web server performing ldap requests on its own depending on your setup.

Independent from LdapContrib and Foswiki itself there is a small perl utility in <wiki-install-path>/tools/ldaptools that can be used to explore the records as returned by your LDAP server on various search requests. This file is easy to understand and should be modified with a text editor before using it for the first time to reflect the specific settings required to connect your LDAP server.
