Pam_krb5 can be configured to convert winbind usernames back into
principal names, by means of some regexp matching and template filling
magic.  It it 'underdocumented' - perhaps you even need to grab the
source RPM and look there?  I can't remember where I found out about it.
I have pam_krb5 2.1.8-1 working very nicely.  Here's the excerpt from my

 pam = {
   debug = false
   ticket_lifetime = 36000
   renew_lifetime = 36000
   forwardable = true
   krb4_convert = false
   mappings = RILINUX-(.*) $1 at RILINUX.COM RILINUXEU-(.*)

The 'mappings' is a set of regexp-template pairs.  In my example,
usernames that start with
RILINUX- are mapped into principals in RILINUX.COM, usernames in
RILINUXEU- are mapped into the

If you have lots of domains you can do things like (untested):

   mappings = RILINUX([^-]+)-(.*) $2@$1.RILINUX.COM
