Is there any hidden switch available to force horde to punify IDN
domains before it passes the credentials forward to authentication?
A preauthenticate hook?
Ah, a hook would be a solution! I missed that point, sorry.

I'm using the SQL backend.
Since my user table is also used by Postfix, and Postfix requires the 
punycode notation of the IDN domains, I have to store it in that way 
in the table.

Once logged in, horde encoded the name correctly to display it in IDN 
version without any configuration - so I hope I can autodetect IDN 
logins and convert them into punicode as horde does it to display the 
user email address.

thanks.

This has nothing to do with Horde, and you didn't even mention your 
authentication backend. Login credentials with non-ascii characters 
don't work in a portable way, because there almost zero authentication 
schemes which have knowledge of charsets.

Using emailadresses containing IDN domains as login credential with horde:

To log into horde the punycode variant of the domain has to be used. 
It is not possible to log in with the IDN version which would be very 
comfortable for users having IDN domains.

Once logged into horde, the punycode emailadress is correctly parsed 
and displayed as IDN version of the eMailadress. (displayed in the 
upper right corner)

Is there any hidden switch available to force horde to punify IDN 
domains before it passes the credentials forward to authentication?

Thanks,
Torben
