r1588: This is one of the more pathetic patches I ever checked in. Many hours of
coding have passed, but I could not find a way to get the OpenLDAP libraries
to reliably time out on any of the queries we make, *and* get correct error
returns. No, async calls and ldap_result does NOT work, or I was simply too
stupid to correctly interpret the OpenLDAP manpage and source.

We can not allow to hang indefinitely in an ldap query, especially not for
winbindd. "ldap timeout" now specifies the overall timeout for the complete
operation, that's why I increased that to 15 seconds.
