[Dovecot] Need a little shadow to MySQL conversion help

[Marc Perkel]

This seems to work fine for me. Thanks to everyone for your help.

default_pass_scheme = CRYPT

password_query = \
  SELECT user_name, domain_name, password \
  FROM users WHERE user_name = '%n' AND domain_name = '%d'


But - slightly off topic. Suppose I wanted to add some kind of date/time 
field to MySQL so that I can records the date and time of the last 
login. Is there an easy way to do that?
