Yeah, I'm sure it will. I wish I could do it in one query though.. How 
often does the ptloader get called on? Will the pts cache here help at 
all? What exactly does the pts cache do? ( I realize that it probably 
caches authorizaton info, but is it always consulted first, before 
asking the ptloader to look up the information again?)

I don't see this in ldap.c. The identifier group:xxx gets passed into 
pts as the identifier and rejected by the canonicalizer because of the 
colon. So the canonicalized identifer is null throughout the rest of the 
code. I don't see a test for group: anywhere ( or in afskrb.c either ). 
So assuming that we just want to make sure that the group name is valid, 
and that the canonicalizer should be fixed to recognize group:xxx 
syntax, what then am I suppose to do with it? Returning NULL seems to Do 
Bad Things, and I don't see an entry for canonicalized group in the 
auth_state struct..
