No, the server can only support certain realms, and advertises a 
subset of those.

The client can only use a supported realm on the server, but it might 
not be one that's advertised.

In Cyrus SASL, all realms are advertised, therefore there are no 
legal realms the client could choose which are not in the server's 
message.
