Subject: ITS#7532 - Add new function ldap_connect().
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=29f6260364df588c876d922ffcc3c429e3b4f062;p=openldap

ITS#7532 - Add new function ldap_connect().

This function is used to manually establish a connection after
a call to ldap_initialize(). This is primarily so that a file
descriptor can be obtained before any requests are sent for the
purposes of polling for writability.
