*Hi Milan,
I know RedHat's IPA server can do this, but that based on 389 Directory Server. Also, have a look here: http://www.mail-archive.com/sssd-devel@lists.fedorahosted.org/msg06902.html
This guy succeeded, but with a combi of posixGroup and groupOfMembers. I'll try to see if I get you suggestion working, although I don't like to change the default schema too much.
Ideally nss_ldap should give us more options in this regard.
*Greetz,

Hi Fred,****
Have you tried ‘hacking’ your schema, and change for example ‘STRUCTURAL’ to ‘AUXILIARY’. In that case you would be able to specify both posixGroup and groupOfMembers, or even use groupOfNames.****
Have a lok at this****
http://serverfault.com/questions/224750/dn-based-linux-groups-from-ldap/2262...
I am also struggling to understand what is the best way to implement this, and I would really appreciate if somebody already done it, and can share the idea.****

Howard,
So, what is the right way? Could you give me an example how to set this up or give me a reference to a good source on this?
Thank you!

Hi llg,
I fail to see how this solves my RBAC need.
Let me give an example:
Say, personA is in ou DeptA. Then, ideally personA would based on being in this ou, become member of group webserver
No, when I move personA to ou DeptB, this would mean that, on the next login, it looses it's membership to group Webserver, but now becomes member of ie group mailservers
This way, you implement security policies based on the role of a person.** **
This is not the right way to implement roles. Generally DNs are intended to be constant (though obviously they are allowed to change, changes should be infrequent).****
How could this ideally be done with OpenLDAP?

Hi, persons should use inetOrgPerson and PosixAccount schemas : gidNumber gives primary group.
Then define specific branch ou=posix based on PosixGroup schema and add the uid of the person in memberUid multiple values attribute to specify secondary gid.

Hi all,
warning: openldap newbie..
is it possible to have a person put into an OU and, because of this, will become member of some group in such a way that this group shows up in linux using "id". This to implement some form of RBAC. I found GroupofMembers, but that has nothing to do with OU's. Also, it seems posixGroup and groupOfMembers objecttypes are no longer allowed together because the are both STRUCTURAL.
In AD this is possible.
