Re: Using LDAP with postgresql 8.2

There are ways to enable it, but in general, yes, you're right. In AD you have to do some magic to bind if you're not part of the actual AD forest.

Hi,
I'm not an AD expert myself, but I've read somewhere, that AD disallows
simple binds without using ssl.
You could try enabling ssl on AD, or try the krb5 authentication method
for pg.

Good Luck
