Hi,

after upgrading from 2.0.15 to 2.0.16 authentication with vpopmail won´t work anymore.

2.0.x and 1.2.x works (this output is from 2.0.15):

2.0.16 doesn´t work:

Just a wild guess - but is it possible that the reason could be found here: http://hg.dovecot.org/dovecot-2.0/rev/b99da8b1ecef

Thanks for any suggestions.
