I believe that similar questions have been posted to the list, but I can't recall seeing a resolution to this problem. I have a number of Solaris and Linux machines that are configured to use Kerberos to authenticate against our Windows 2003 Active Directory. The problem is that when I use SAMBA 3.x to join the machine to the domain, the Kerberos authentication breaks. One workaround is to change the machine name is smb.conf to something like server-shares, but this is confusing for users and it will be very time consuming for me to remap everyone's network drives. Is there any way to use the existing krb5.keytab, or do you have any other suggestions or workarounds? Thanks.
