[horde] Trailing spaces in username

[Toomas Aas]

Hello!

I have Horde 3.3.8 and IMP 4.3.7 installed. Horde is configured to use  
IMP for authentication and IMP is authenticating against Cyrus IMAP  
server.

Today one user called me and said that she's been unable to send any  
mail for 3 days. Whenever she composed a new mail and clicked "Send",  
she received an error saying that the From address is not valid.

I have usernames in Cyrus formatted as firstname_lastname. The address  
in the error message was "firstname_lastname @mydomain.com", note the  
space between name and @. I had the user log in again making sure that  
she enter the username without trailing spaces, and the problem was  
solved.

Looking at the horde_prefs database table it seems to me that more  
than one user is being or has been affected by this, because there are  
rows with different amount of spaces between name and @ sign in the  
pref_uid column for several users. It seems that IMAP user 'jane_doe'  
can successfully authenticate to horde using username 'jane_doe ',  
'jane_doe  ' or 'jane_doe      ', the IMAP server authenticates her  
successfully but Horde considers each of them a different user. Is  
there something I can configure correctly to avoid this issue?
