[Dovecot] passdb/userdb args

[Daniel L. Miller]

Thank you - I was thinking perhaps a wrapper script would be necessary.

How do the multiple userdb/passdb sections work?  Once a match is found, 
does processing stop?  Or are multiple matches combined?  Does the 
"userdb static" set defaults which could be used for the userdb ldap?
