Actually I happen not to understand the above :-(  I thought PLAIN is a 
plaintext schema while CRAM-MD5 is non-plaintext schema and it's 
impossible to have the same password in mixed schemas stored in one 
database used for different authentication mechanisms (i.e. PLAIN and 
CRAM-MD5). Moreover there is no fallback using mechanism other than 
PLAIN. What am I missing here?

Yes, the password is the same in both cases, but it is stored twice: as 
a MD5 hash and as a CRAM-MD5 hash.
