LDAP Group Synchronization


  • Nested groups are not implemented, send a pull-request if you need this feature.


  • Have LDAP authentication properly configured
  • Use a LDAP server that supports memberOf or memberUid (PosixGroups)

Define automatically user roles based on LDAP groups

Use these constants in your config file:

  • LDAP_GROUP_ADMIN_DN: Distinguished names for application administrators
  • LDAP_GROUP_MANAGER_DN: Distinguished names for application managers

Example for Active Directory:

define('LDAP_GROUP_ADMIN_DN', 'CN=Kanboard Admins,CN=Users,DC=kanboard,DC=local');
define('LDAP_GROUP_MANAGER_DN', 'CN=Kanboard Managers,CN=Users,DC=kanboard,DC=local');
  • People member of “Kanboard Admins” will have the role “Administrator”
  • People member of “Kanboard Managers” will have the role “Managers”
  • Everybody else will have the role “User”

Example for OpenLDAP with Posix Groups:

define('LDAP_GROUP_BASE_DN', 'ou=Groups,dc=kanboard,dc=local');
define('LDAP_GROUP_USER_FILTER', '(&(objectClass=posixGroup)(memberUid=%s))');
define('LDAP_GROUP_ADMIN_DN', 'cn=Kanboard Admins,ou=Groups,dc=kanboard,dc=local');
define('LDAP_GROUP_MANAGER_DN', 'cn=Kanboard Managers,ou=Groups,dc=kanboard,dc=local');

You must define the parameter LDAP_GROUP_USER_FILTER if your LDAP server use memberUid instead of memberOf. All parameters of this example are mandatory.

Automatically load LDAP groups for project permissions

This feature allows you to sync automatically LDAP groups with Kanboard groups. Each group can have a different project role assigned.

On the project permissions page, people can enter groups in the auto-complete field and Kanboard can search for groups with any provider enabled.

If the group doesn’t exist in the local database, it will be automatically synced.

  • LDAP_GROUP_PROVIDER: Enable the LDAP group provider
  • LDAP_GROUP_BASE_DN: Distinguished names to find groups in LDAP directory
  • LDAP_GROUP_FILTER: LDAP filter used to perform the query
  • LDAP_GROUP_ATTRIBUTE_NAME: LDAP attribute used to fetch the group name

Example for Active Directory:

define('LDAP_GROUP_PROVIDER', true);
define('LDAP_GROUP_BASE_DN', 'CN=Groups,DC=kanboard,DC=local');
define('LDAP_GROUP_FILTER', '(&(objectClass=group)(sAMAccountName=%s*))');

With the filter given as example above, Kanboard will search for groups that match the query. If the end-user enter the text “My group” in the auto-complete box, Kanboard will return all groups that match the pattern: (&(objectClass=group)(sAMAccountName=My group*)).

  • Note 1: The special characters * is important here, otherwise an exact match will be done.
  • Note 2: This feature is only compatible with LDAP authentication configured in “proxy” or “anonymous” mode
