#87 Resource leaks in ldap external lookup

[Enrico Scholz]

ldap_lookup() calls 'return NULL' in error case without freeing the allocated LDAP handle. This leaks a filedescriptor and brings OpenLDAP in a state that all subsequent lookups fail with

| External Lookup: Backend initialization failure: Success (0)

I detected this problem when an LDAP server was unreachable.

Hello Enrico,

Can you confirm that this problem only happens when using starttls to communicate to the Ldap server?

I am using starttls when connecting to LDAP server. But I can not say whether it happens only in this situation.
