I've been fighting with this since long time now. Reading posts & archieves, having no luck beyond this point.......but now a bit desperate to get this done as I am running out of time now. Any help in this matter is truly appreciated. I attempted to use following ldap.conf settings, but still get auth failures upon doing ssh w/ ldap user*.

Hi all, I'm stuck in the same issue as Serge Fonville. I have created new Auxiliary objectclass 'testobj' with 'host' attribute & added it to the ou=Groups.Then created 2 entries under Groups as below & assigned members to those groups.
dn: cn=qagroup,ou=Groups,dc=test,dc=com cn: qagroup gidNumber: 4 objectClass: posixGroup objectClass: testobj host: x15f12.test.com memberUid: uid=ldap1,ou=Users,dc=test,dc=com memberUid: uid=ldap2,ou=Users,dc=test,dc=com
dn: cn=admin,ou=Groups,dc=test,dc=com cn: admin gidNumber: 0 objectClass: posixGroup objectClass: testobj host: x15ubuntu.test.com memberUid: uid=ldap3,ou=Users,dc=test,dc=com memberUid: uid=ldap4,ou=Users,dc=test,dc=com
Now *which parameter in ldap.conf or any other files I host machine should I modify and how,* so that members from qagroup or admin groups only get access to host mentioned in their respective attributes ??
Thanks in advance Shamika

Or you can create your own Aux. object class that includes the host
attribute then you just have to modify the ldap.conf for the machine to restrict user authentication.

If you are using ssh and pam can be done like this:
# tail /etc/ssh/sshd_config
# Allow client to pass locale environment variables AcceptEnv LANG LC_*
Subsystem sftp /usr/lib/openssh/sftp-server
UsePAM yes
# Restringir acesso ao grupo local 'suporte' e a grupos LDAP AllowGroups suporte "SSH UDSL"
where "SSH UDSL" is a Group in LDAP, and "suporte" is a local group.

Hi,
While setting up an LDAP server. I noticed that it is not possible to add a host attribute to a posixGroup.
Is there a way to limit a user what host they can logon to based on their group membership?
Thanks in advance

Serge Fonville
