Here are the steps and explanation (via links) on how an LDAP (or Active Directory) user gets mapped to an Artifactory LDAP group.
- Setup LDAP filter (or Active Directory)
- Setup and Import LDAP Groups
- Create permission rules to the LDAP Groups (also refer to Best Practice for setting Permission Target – requires Support Portal login)
- Login to Artifactory using a LDAP user.
Here is a video on how the LDAP group mapping is done (showing on 3.x version, but the concept is the same: https://www.youtube.com/watch?v=IdZz0R6laxA
How does it work?
Once an LDAP group is mapped to Artifactory, Artifactory examines each LDAP group to see if a user belongs to the group or not by contacting the LDAP server. Once Artifactory finds that the user belongs to the group, then it lets the user have the permissions that have been given to the group by an Artifactory administrator.
What’s the advantage of using LDAP Group?
The Artifactory administrator does not have to manage permissions for each user. Instead, the Artifactory administrator needs only to manage the permissions given to each LDAP group, while maintaining the LDAP group at the LDAP server.
Where does it search and how is the Search Base is used?
LDAP Group settings make the LDAP queries relative to the “LDAP Setting” that is selected. Thus, the Search Base at the LDAP Group Settings page should be set relative to LDAP URL. For example, if LDAP Settings has the LDAP URL as ldap://abc and ‘LDAP Group Search Base’ as ou=groups, then LDAP Group’s searches will be made relative to ldap://abc/ou=groups .
Example of using Static Mapping Strategy
The following example shows that the group has two members, kwinters and trigden, as the group’s uniqueMember attribute. Once this group is imported, any users who are part of this group’s uniqueMember attribute, and meets the conditions set at the LDAP setting will automatically join the group. If the group is given any permissions to it, then the users will automatically inherit the permissions. Since this is Static mapping, “PD Managers” group is aware of its members; however, the users are not aware of the groups they belong to.
Example of using Dynamic Mapping Strategy
The following example shows that the member has one group, Domain Guests. This is one of the user’s LDAP attributes. Once this group is imported, any users who have the LDAP attribute as “memberOf” Domain Guests, and meets conditions set at the LDAP setting will automatically join the group. If the group is given any permissions to it, then the users will automatically inherit the permissions. Since this is Dynamic mapping, the user, joshua, is aware of what groups it belongs to, but the group object, Domain Guest, is not aware of their members (;although, Windows have cross-referenced at the group by also using ‘member’ attribute, it is not required).
Example of assigning permission targets to imported LDAP groups
After the groups have been imported, you can go to Admin => Security => Groups to confirm that those ldap groups show up there. Since it is not Artifactory’s internal groups, it will have “External” checked. As you can see in the screenshot below, it does not have any permission targets associated with it yet.
Now, let’s create Read permission to domain guests and Read, Annotate, Cache permissions to pd managers at Admin => Security => Permissions. After selecting repositories, go to Groups and assign permissions as you wanted.
Example of verifying the permission targets
After saving it, you can login using an LDAP user who belongs to pd managers LDAP group. The user will then be able to cache any remote repositories as well as reading from any remote and local ones that the permission target was associated with. For another LDAP user who only belongs to the domain guests group, it will not be able to cache any artifacts that have not been cached by others. However, the user can still download any artifacts that have already been cached or exist in a local repository if the repository belongs to the permission target’s repository list.
Once the user logs into Artifactory, an Artifactory administrator can verify the user’s groups and permissions at Admin => Security => Users => find the user ID
Additional Q & A
Q: Does LDAP group’s “Import” button sync members of a ldap group?
A: No, it just maps the group to Artifactory. Members of the group can only be added if you have “Auto Create Artifactory Users” enabled at LDAP Setting AND the user logs into Artifactory at least once. Also, Artifactory never saves the LDAP user’s password.
Q: Which mapping strategy should I choose?
A: It depends on how your LDAP is structured. For example, you may find that Static method gives you a faster login experience if the LDAP query returns smaller results by using it. The end goal is to find the most efficient search. Please consult with your LDAP administrator for further advice.
- See LDAP attributes found for the user (e.g. run “ldapsearch joshua”) and compare it with the group filter
- In Artifactory, go to Admin => Security => LDAP Settings => Select and Edit your LDAP setting => Enter a test username and password => Click on Test Connection
- Enable more logs by adding the below debug loggers at the end of the $ARTIFACTORY_HOME/etc/logback.xml file. Enabling the debug logs does not require restarting Artifactory.
