Re: Membership of Roles

[Jonathan Vaughn <jonathan@xxxxxxxxxxxxx>]

memberOf plugin and adding inetuser to users is mainly to allow easier support for nested groups, as instead of having to search top down from a group and any groups it includes (and potentially detect and avoid any loops) to find all users of a group, you can simply query against the user itself and check for a memberOf=(group dn). In my experience most software doesn't handle nested groups at all, some supports memberOf (either directly or indirectly, sometimes you can just configure the search and attribute matching to work with it even though it isn't explicitly supported), and some software is hard coded to only work with groups and fails to handle nesting.

If you're just trying to get a user to show up as a member of the group, and they're a direct member (uniquemember), then none of this should matter - it should just work. Does the new group have all the same objectclasses as the existing one? Maybe for example, your software is looking for objectclass=posixgroup but you just have groupofuniquenames so it doesn't work correctly?

Actually, now that I look back at the conversation history, are you still filtering the group search on objectclass=ldapSubEntry ? Isn't that for roles, not groups? Maybe there's no ldapSubEntry operational attribute on the new group for whatever reason?

I haven’t been able to get membership of groups to work in either Liferay or blog system. The error has to be with my setup groups or the memberOf plugin. All users have objectclass inetUser. I enabled the memberOf plugin before creating the test group, and also ran the fixup script when I found that the group was not working.

Interestingly the blog system recognizes groups that were part of the initial installation of 389. The group that I need to recognise uniquemembers for is the group I created call blogEditorGroup.

 

Screenshot from blog system test of communications with ldap. Note the group = blogEditorGroup, does not recognise any of the three members created for the test.

Jonathan,

That could be the root of the groups issue. I enabled the memberOf plugin after creating the groups and users.

I will be testing in a few minutes.

If you had your users and groups created before enabling memberOf, you'll need to modify their group membership (per user, easiest would be to add all to a temporary group then remove the group after memberOf populates) to trigger memberOf creation. It only gets set on changes, and won't autogenerate for existing memberships until a change occurs. It WILL regenerate all memberships even if you change just one, so you can just throw everyone into a group as I said to trigger it. There was a script in some FDS / 389DS howto someplace that was supposed to background trigger it, but I never got it to work.

Hi Rich,

I had added the inetUser objectclass on the test cases of groups that failed. I was wondering if I had incorrectly configured arguments of the memberOf plugin. I will read the documentation again.

 

I should be done rebuilding my instance of 389 in an hour or so.

Hi Rich,

I am having the same problem with groups, so I am wondering if I have groups configured correctly. Especially the configuration of the memberOf plugin.

https://access.redhat.com/site/documentation/en-US/Red_Hat_Directory_Server/9.0/html/Administration_Guide/Advanced_Entry_Management.html#groups-cmd-memberof

Especially this part:

6.1.4.2. Object Classes Which Support memberof Attributes

The most common people object classes — such as inetorgperson and person — do not allow the memberOf attribute. To allow the MemberOf Plug-in to add the memberOf attribute to a user entry, make sure that that entry belongs to the inetUser object class, which does allow the memberOf attribute.

Similarly, if an attribute other than memberOf is used in the user entry, then make sure that the user entry belongs to an object class that allows that attribute.

 

I’m in the process of reconfiguring my instance of ldap, as it was misbehaving after I tried out various configuration to get roles and groups to work.

My configuration:

LDAPAuthBindDN cn=Directory Manager (will replace with application user account once phase one integration is completed)

LDAPAuthPassword xxxxxx

LDAPGroupFilter (objectclass=ldapSubEntry)

LDAPUserEmailAttribute mail

LDAPUserFullNameAttribute cn

LDAPUserGroupMemberAttribute nsrole

I think this is going to be problematic, and may not work at all.  With groups, there is an actual group entry, which lists all of the members.  With roles, the role entry does not list all of the members.  So a query like
SRCH base="ou=customers,dc=xxxx,dc=com" scope=2 filter="(&(|(member=cn=xxxxrolecommentertest,ou=customers,dc=xxxx,dc=com))(objectClass=ldapSubEntry))"

will not work because there is no role entry which lists it's members in a "member" attribute.

If you can configure it to search all of the users, you might be able to do a search like

SRCH base="ou=customers,dc=xxxx,dc=com" scope=2 filter="(nsRole=cn=xxxxrolecommentertest,ou=customers,dc=xxxx,dc=com)"

Roles will automatically populate each user's entry with the nsRole attribute.  This attribute lists all of the roles to which that user belongs.  nsRole is an operational attribute, so you must explicitly request it on the command line if you want to see it (e.g. in an ldapsearch command).

Hello

I am testing integration of 389-ds with a blogging system. I plan to use roles instead of groups to automatically give users rights to service on the blog system. However, I am having problems with the system identifying members of roles. I need help with defining the correct search parameters to identify which roles a uid or cn is a member of.

 

From within the blog system I’m using LDAPGroupFilter (objectclass=ldapSubEntry) to list the roles. The roles list correctly as groups within the blog system.

From within 389 the members of roles are configured as filtered, and I can see the configured members using the Directory Server GUI.

 

The blog system is not identifying members of roles when it does its search against 389. Note, users can log into the blog system using the accounts created on 389. I don’t think I am applying the correct search criteria to identify group membership. I need advice on creation of the correct search criteria for membership of roles/groups.
