(ITS#4927) pam_authenticate through ldap causes cups to crash

cups 1.2.10 invokes pam_authenticate which on my system goes through ldap. When
cups tries to authenticate it is dumping core. The backtrace seems to show that
it is crashing within the OpenLDAP code. I'm using the PADL libraries, not the
native Solaris libraries.
