Hi, i have a "strange" situation. I want to use some Linux Box in a AD structure using Winbind to access to some shares with user permission. I've done correctly on a RH ES 4.0 and i'm using thin machine with no problem. I've done the same configuration on a CentOS 4.4 but it doesn't run. When i access from a W2K station i have to insert a username/password to access on station. On Linux i receive in station log (machine name) this messages "reply_spnego:kerberos username ShortDomainName\UserName is invalid on this system". I've tried to copy same config files (nsswitch, krb5.conf, system-auth,smb.conf) from the other machine with no change. I've tested net ads and wbinfo to check if comunications with AD is correct, and it seems to be ok. I suppose that Kerberes doesn't talk with Winbind but i don't understand what's the problem. thanks
