* ldapu_find

* scope scope for the search. One of
* LDAP_SCOPE_SUBTREE, LDAP_SCOPE_ONELEVEL, and

* filter LDAP filter
* attrs A NULL-terminated array of strings indicating which

* attrsonly A boolean value that should be zero if both attribute

* Return Values:
* LDAPU_SUCCESS if entry is found
* LDAPU_FAILED if entry is not found
