Hello all I'm using the fedora directory server for centralized authentication , and i have made users with posix account and i put them in ou=People like this : --------------------------------------------------------------------------------------------- # alexadu, People, pol.mediaimage.ro dn: uid=alexadu,ou=People,dc=pol,dc=ro givenName: Alexandra sn: Dumitru loginShell: /bin/bash uidNumber: 1069 gidNumber: 100 objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetorgperson objectClass: posixAccount uid: alexadu cn: Alexandra Dumitru homeDirectory: /home/alexadu ------------------------------------------------------------------------------------------ and after that i made some groups in ou=Groups like this : ----------------------------------------------------------------------------------------- # Server1, Groups, pol.ro dn: cn=Server1,ou=Groups,dc=pol,dc=ro description: group for users that have access on server 1 objectClass: top objectClass: groupofuniquenames uniqueMember: uid=lauru,ou=People,dc=pol,dc=ro uniqueMember: uid=alexadu,ou=People,dc=pol,dc=ro cn: Server1 ---------------------------------------------------------------------------------------- and my ldap.conf looks like this : URI ldap://lacatzel.pol.ro port=389 BASE dc=pol,dc=ro host lacatzel.pol.ro TLS_CACERTDIR /etc/openldap/cacerts TLS_REQCERT allow scope sub bind_policy soft #pam_password exop pam_filter objectclass=posixAccount pam_login_attribute uid pam_member_attribute memberUid pam_groupdn cn=Server1,ou=Groups,dc=pol,dc=ro pam_check_host_attr yes nss_default_attribute_value loginShell /bin/false nss_base_passwd ou=People,dc=pol,dc=ro nss_base_shadow ou=People,dc=pol,dc=ro nss_base_group ou=People,dc=pol,dc=ro --------------------------------------------------------------------------------------------- now i want to restrict some users to servers based on groups but my pam_ldap does not help me to do that , I'm using my old friend "www.google.com" to help me in this problem but with no luck ..... all my users have access to this computer .... so , if i understand wright all i have to do is create users with posix account and after that create groups and put the users in that group but this does not work ..... any ideas ? anyone use FDS for what i intend to do ? Thank you for your time ..... Bogdan
