Apache startup problems

After spending the better part of a day trying to track this problem down, I figured I'd be nice and share the fix, since google wasn't helpful. I was trying to fix a previously working apache installation and found that I was unable to authenticate using LDAP. With the apache logging set to debug, I received the following messages.

At apache startup:
[Wed Apr 06 08:56:30 2011] [debug] mod_authnz_ldap.c(1010): [2999] auth_ldap url parse: `ldap://ldap.blissfulidiot.com/ou=people,dc=blissfulidiot,dc=com?uid?sub?(clxEnabled=TRUE)', Host: ldap.blissfulidiot.com, Port: 389, DN: ou=people,dc=blissfulidiot,dc=com, attrib: uid, scope: subtree, filter: (clxEnabled=TRUE), connection mode: not using SSL

At authentication attempt:

[Wed Apr 06 08:57:58 2011] [debug] mod_authnz_ldap.c(403): [client 10.0.3.6] [5604] auth_ldap authenticate: using URL ldap://ldap.blissfulidiot.com/ou=people,dc=blissfulidiot,dc=com?uid?sub?(clxEnabled=TRUE)

[Wed Apr 06 08:57:58 2011] [info] [client 10.0.3.6] [5604] auth_ldap authenticate: user tom authentication failed; URI / [LDAP: ldap initialization failed][Unknown (private extension) error]

The solution for me on FreeBSD, rebuild the apr port.
