Re: regarding referral

["Bharat Tewari" <tewari@wipinfo.soft.net>]

Hi
Added to this is the following investigation done, checked with the
ldap_chase_referrals() function, it only parses for the new dn name and not
for any other attributes sent along with the referral result. And on top of
that the scope parameter is ber encoded so if i have to change it i need to
follow some code similar to re_encode_request() done for the change in the
dn name :( , is it that much work, is there a faster solution to this
problem??
thx. a lot for any response or else i am doomed.
bye
