[horde] Username and pref_uid

[Christian Schoepplein]

Hello,

I am updating a very old horde installation to the newest packages, 
everything fine so far. But one thing regarding username and the 
pref_uid, which is used for example to identify personal preferences 
in the horde_prefs table, is causing me headaches :-(.

To log in to horde and imapservers the login firstname.lastname shall be 
used and the mailaddress of the users 
shall be firstname.lastname at domain.tld. This is working so far, but with 
that kind of setup in the horde_prefs table all user settings are stored 
with the pref_uid firstname.lastname.

Now I am looking for a simple solution to add a additional string to 
the pref_uid, so that it looks like this: 
(firstname.lastname.additional_string

I've tried to do this using the authusername hook and I was able to 
change the string, but unfortunatly this is changing the userId variable 
in general and the additional string is also added to mailaddresses, 
e.g., so a mailaddress loks like 
firstname.lastname.additional_string at domain.tld now.

Is there an easy way to use another pref_uid then the userId which is 
entered while login into horde? Or to ask it another way: Can I 
initialize a different pref_uid then the userId everytime a user is 
login in?

Cheers,

  Schoepp
