Re: back-ldap and saslauthd err=4

[Andrew Reilly <andrew.reilly@gmail.com>]

Version 2.2.23 in case of the back-ldap instance, and varying in case
of the back-bdb instances including versions 2.1.29 -> 2.2.23.

When I can I will set up a test instance of 2.2.24 back-ldap and
enable server logging at level 256 + 4.

thanks for the response,
Andrew
