For the use of the kerberized IMAP-Server cyrus, we need to map a SPN 
imap.hostname to a service account in AD.

I tried this with ktpass but mapping always failed with an error and the 
SPN was not attached to the account (I tried this with new accounts 
also).

But it was possible to attach imap/hostname to the same account. Hence 
there seems to be some problem which is related to syntax of SPNs 
allowed in AD.

To your question about using computer accounts:

In W2k-Server I have succeeded to map a SPN to a computer account by 
mapping to the user host$, where host is the hostname. This did not work 
when I recently tried on a 2003 Server.

Dirk.
