Active Directory Auth Plugin
The Active Directory Auth Plugin is a password store for the AccountManagerPlugin that provides authentication and groups from Active Directory.
Users are authenticated by performing an ldap_bind against the AD server using their credentials.
- One can specify a group which users must be a member of in order to log in.
- Additionally, one may specify an admin group. If a user is a member of the admin group, then they will automatically be granted the TRAC_ADMIN permission.
- Finally, ActiveDirectory groups are extended into the trac namespace. They can be used to extend permissions by AD group.
- AD groups are prefixed by @
- group names are lowercase and spaces are replaced with underscores.
The Active Directory Auth plugin will also pull the email address and display name from Active Directory and populate the session_attribute table. See Populating ''Assign To'' Drop Down in Trac for more information on why.

All config options go under the [account-manager] config heading. Options for this module are:
[account-manager] #to use this module with AccountManager, ADAuthStore must be enabled inside of AccountManager password_store = ADAuthStore #define the Active Directory host address here. A port other than default is set as #-- hostname:port ad_server = adserver.example.com #-- the Active Directory's base DN to search from, this is likely just your domain base_dn = DC=example,DC=com #-- the user/password to search active directory from, it must be a valid bind_dn = firstname.lastname@example.org bind_passwd = ldapuserpassword #-- show disabled users # remember users MUST have logged in to get into the session table before they # show up. show_disabled_users = 1 #-- timeout for an ldap operation before in seconds ldap_timeout = 5 #-- the default charset for the ldap server charset = utf-9 #-- the DN (distinguishing name) for the group that contains users that can login to Trac # if this isn't specified then any valid user in active directory is accepted auth_group = CN=Alltechs,OU=Mail enabled groups,OU=Email,DC=serverplus,DC=com #-- the DN for the group that contains users that should have the TRAC_ADMIN # permission. If this option is not given, no user groups will be give the # TRAC_ADMIN permission. This this option is enabled you must specify the # UserExtensiblePermissionStore as the trac permission store, such as: # [trac] # permission_store = UserExtensiblePermissionStore admin_group = CN=Administration,DC=example,DC=com #-- cached entry timeout in seconds cache_timeout = 90 #-- memorycache size in entries memcache_size = 100 #-- memory cache prune size in percentage memcache_prune_percent = 5 [trac] permission_store = UserExtensiblePermissionStore
If you are unsure of what the DNs for your groups are, you may want to use an LDAP browser to inspect your Active Directory schema to find out a group's DN.
If you see Trac throwing an exception similar to "OPERATIONS_ERROR: In order to perform this operation a successful bind must be completed on the connection" when you know the bind user/pass is correct you will want to try connection to active directory on port 3268. This may happen when AD is running across multiple machines.
