There seem to be 3 places that have to be dealt with:
 1) login
 2) message delivery
 3) mailbox names

It seems like 1 is very localized and a trivial change in 
auth_canonifyid (if it isn't appropriate for Kerberos, then the switch 
could just be ignored in auth_krb*.c) .  2 is easy enough and a small 
variant of Henrique's patch should do it. 3 is much harder, since you 
potentially have to handle select Shared Folders/user/JTampli/Test to 
resolve to user/jtampli/Test and similar situations.  I think it is less 
of an issue because most clients are just going to show the user what 
LIST/etc return (and any running altnamespace won't see them except for 
other users that have granted permissions to one of their folders), so I 
would be happy with a patch that solves only 1 & 2 (and in fact I will 
probably implement it myself for local use if nobody is interested in 
getting into the official distribution).
