Password changing on an blackbox imap server

[christoph]

Hi,

does anybody habe an idea, how to implement password changing on an cyrus 
imap server? I don't want to grant my users access to a shell to call the 
program saslpasswd themselves.... 

I'm using the sasldb configuration, because that enables me, not to have 
the client entered as a system user. The only disadvantage is, that I must 
have an administrator, who sets passwords for clients, but thats not wanted 
on a blackbox solution with web interface.....

Regards
Christoph
