There are two SASL plugins dealing with login and user names:

1. canonical
   translates the given username to an internal username, which cyrus imapd 
uses as mailbox name (with user prefix "user.").
2. auxprop
   takes the given username, retrieves the stored secret, and returns it to 
the SASL library. The auxprop can also do the mapping of the given username 
to another user name schema used in the authentication/secret database. It 
passes the given username unchanged to the imap daemon which will be the 
mailbox name then.

In our setup, users do log in with their e-mail-address, but the mailboxes 
have our internal uid as name. A canonical plugin does the translation. In 
your case, a canonical plugin should convert the username into the sid, 
cyrus imap will use that as mail box name.
