Hello,

I have two questions on same line, and these answers will be very helpful.

1)

The MemberOf plugin works wonderful using SSSD at client side, however, is it possible to have the same kind of Control at the Server side?

I mean, could I have the ability to control user's Authentication on a Host machine based on it's group or other parameter very much the same way that now I am doing with memberOf/sssd.conf at the Host Machine.

Not exactly - http://port389.org/wiki/Howto:Netgroups

2) 

I know this is not IPA group, in case someone knows. Does IPA supports that feature at the server side? or using sssd.conf at the host machine?

Any pointers to RTFM would also be helpful. :-)

Thanks

Chandan

Hello,

So far I have been managed to do some setup of 389 server, thanks to prompt community.

Now, I am having some trouble in getting the MemberOf plugin work for 389-ds-base-1.2.11.15-11. When I add a user into a group, the memberOf attribute is not being added to the user entry.

While googling a bit I came across an older post of this group

http://www.redhat.com/archives/fedora-directory-users/2009-December/msg00165.html

based on that, I checked dse.ldif and the Plugin configuration also looks good.

Too bad that google didn't send you here:
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Directory_Server/9.0/html/Administration_Guide/Advanced_Entry_Management.html#groups-cmd-memberof

Specifically:
"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."

Even in the link you posted:
"         objectClass: shadowaccount
                objectClass: inetuser
        physicalDeliveryOfficeName: Kennebunk
...
"

dn: cn=MemberOf Plugin,cn=plugins,cn=config

objectClass: top

objectClass: nsSlapdPlugin

objectClass: extensibleObject

cn: MemberOf Plugin

nsslapd-pluginPath: libmemberof-plugin

nsslapd-pluginInitfunc: memberof_postop_init

nsslapd-pluginType: postoperation

nsslapd-pluginEnabled: on

nsslapd-plugin-depends-on-type: database

memberofgroupattr: uniqueMember

memberofattr: memberOf

nsslapd-pluginId: memberof

nsslapd-pluginVersion: 1.2.11.15

nsslapd-pluginVendor: 389 Project

nsslapd-pluginDescription: memberof plugin

modifiersName: cn=directory manager

modifyTimestamp: 20130322162350Z

The way I am adding users :

dn: uid=chandank,ou=People,dc=ma,dc=net

objectclass: person

objectclass: inetorgperson

objectclass: posixAccount

cn: Chandan

sn: k

givenName: chandank

uid:chandank

uidNumber:5006

gidNumber:5006

objectclass: mepOriginEntry

mepManagedEntry: cn=chandank

homeDirectory: /home/chandank

loginShell: /bin/bash

The way I am adding them into a group:

dn: cn=sys,ou=Groups,dc=ma,dc=net

changetype: modify

add: uniqueMember

uniqueMember: uid=chandank,ou=People,dc=ma,dc=net

And after I have added the user I am expecting an MemberOf attribute entry in the user entry itself. I am not sure whether it is the right way to do so.

For the records: Having MemberOf attribute in the user entry would allow me use ldap Access filters in sssd.conf file eg.

"ldap_access_filter = memberOf=cn=allowedusers,ou=Groups,dc=example,dc=com" and hence will be able to restrict users from login on different systems.

Thanks

Chandan
