OpenXchange on OS X Server

This may be he wrong place to post this question.
I’ve followed the tutorial from:
http://www.labo-apple.org/en/articles/os+x+server/s+x+server-261/0/

I am getting this error:

ldap_bind: Invalid credentials (49)
expr: syntax error
LDAP Success
SQL Success
rm: /Users/vmail/alan/.Maildir/new/*: No such file or directory

Does anyone know how to fix this??
