PAP password

[Doug Hardie]

V 2.1.5.  I am having a problem with PAP not using the proper user  
id.  IF the user id is just a plain
<user_id> then it works properly.  However, I have some realms setup  
that have prefixes and suffixes e.g., DUB+<user_id>@lafn.  PAP is  
trying to find the user_id DUB+<user_id>@lafn rather than the stripped  
user id <user_id> and hence it doesn't find a password for the user.   
Everything works just fine if I add Auth-Type := Accept to the users  
file, but thats not a great way to run a railroad.  Obviously I missed  
something.

hints has:

DEFAULT Prefix == "DUB+", Suffix == "@lafn", Strip-User-Name = Yes
         Hint = "SlipStream"


What have I missed?
