Sam Varshavchik has released an update on Christmas day (go figure, what a commitment) to the Courier-Auth daemon, this release correct a couple of minor compiler warnings and errors.:

• cryptpassword.c: Fix compiler warnings
• checkpasswordsha1.c: Fix compiler warnings.
• authldaplib.c (auth_ldap_enumerate): Fix typo.

I’ve tested this release without a problem and my production server is running this version at the moment without a problem.
