by the move to Dovecot we try to alter the password encryption stored  
in the database from MD5 to CRYPT-SHA256 along the Guide at  
http://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes. It's mostly  
working but i still have not found out how to pass the cleartext  
password to the re-encrypting script. According to the HowTo it should  
be enough to add "'%w' AS userdb_plain_pass" to the passdb query, to  
get a environment variable $PLAIN_PASS in the post-login script to  
pass along.
This does not work eg. PLAIN_PASS is always empty. This is Dovecot  
2.0.19 from Ubuntu 12.04 LTS.

Thanks for any help
