Hello, I have two CentOS 5.6 clients I'm trying to join to my Active Directory domain for authentication. I have configured my smb.conf like: realm = SYSLAB.DC idmap backend = rid idmap uid = 10000-20000 idmap gid = 10000-20000 and have been able to join both to the domain via: kinit Administrator at SYSLAB.DC net ads join -U Administrator Then I added krb5 to pam.d auth section and configured passwd, group and shadow in nsswitch.conf for "compat winbind". This works fine on the first configured client, but the second one always says it is unable to resolve the accounts to a uid/gid pair, even though manual tests like "getent passwd Administrator" work. HOWEVER, one oddity in my setup is that the second client is a virtual machine clone of the first... Is it possible that as a result samba joined the second computer with a kerberos property that conflicts with the first client's AD object? Is it not possible to have a cloned virtual machine authenticate in this way at the same time as its original (mac address and IP are unique)? Thanks for any advice you can offer, please cc me when replying as I receive list postings in digest. -- Best Regards, John Musbach
