Hi,
I have a set of servers in which I want to configure ssh access based on the users group membership.
I'm using CentOS 5 and this version of openldap
[root@centos5 ldifs]# rpm -qa | grep ldap openldap-servers-2.3.43-12.el5_7.10 php-ldap-5.1.6-27.el5_7.5 openldap-servers-overlays-2.3.43-12.el5_7.10 openldap-2.3.43-12.el5_7.10 nss_ldap-253-42.el5_7.4 openldap-2.3.43-12.el5_7.10 nss_ldap-253-42.el5_7.4 openldap-clients-2.3.43-12.el5_7.10 [root@centos5 ldifs]#
And this is my ldap.conf
base dc=homelinux,dc=net timelimit 120 bind_timelimit 120 idle_timelimit 3600 pam_groupdn cn=access,ou=Group,dc=homelinux,dc=net pam_member_attribute member nss_initgroups_ignoreusers root,ldap,named,avahi,haldaemon,dbus,radvd,tomcat,radiusd,news,mailman,nscd,gdm uri ldap://127.0.0.1/ ssl no tls_cacertdir /etc/openldap/cacerts pam_password md5
And this is the contents of cn=access
[root@centos5 ldifs]# ldapsearch -x -W -D 'cn=Manager,dc=homelinux,dc=net' -h 127.0.0.1 "cn=access" # access, Group, homelinux.net dn: cn=access,ou=Group,dc=homelinux,dc=net cn: access objectClass: top objectClass: groupOfNames objectClass: labeledURIObject member: uid=nobody,ou=People,dc=homelinux,dc=net labeledURI: ldap:///ou=People,dc=homelinux,dc=net??one?(gidNumber=10060) labeledURI: ldap:///ou=People,dc=homelinux,dc=net??one?(host=jumpbox) [root@centos5 ldifs]#
And this is the contents of the gid 10060 (unixsa)
[root@centos5 ldifs]# ldapsearch -x -W -D 'cn=Manager,dc=homelinux,dc=net' -h 127.0.0.1 "cn=unixsa" # unixsa, Group, homelinux.net dn: cn=unixsa,ou=Group,dc=homelinux,dc=net gidNumber: 10060 description: unixsa objectClass: top objectClass: posixGroup cn: unixsa memberUid: uid=dan,ou=People,dc=homelinux,dc=net memberUid: dan [root@centos5 ldifs]#
And when I try to ssh into this box I get the following:
[kwame@vader ~]$ ssh dan@centos5 dan@centos5's password: You must be a member of cn=access,ou=Group,dc=homelinux,dc=net to login. Connection closed by 192.168.122.225 [kwame@vader ~]$
This is the info for the user dan [root@centos5 ldifs]# id dan uid=10051(uid=dan,ou=People,dc=homelinux,dc=net) gid=10051(dan) groups=10051(dan),10060(unixsa)
Comments? Thoughts? Words of wisdom?
Best regards
