Re: Bind using a user other than organizationalRole user

Hi Dieter, thanks for the reply.

Yeah, the folks @ #openladp were kind enough to help me to debug this issue. It turned out that it was a simple detail (as mostly always :)) -- When I created the ldif, I've put the password in clear text, however, I didn't do anything to tell openldap that it was actually cleartext nor I knew I had to. The whole time I though it had to do with ACLs (OpenLDAP denying read-access to userPassword), but the problem was that OpenLDAP was trying to authenticate using SHA-1, and the password was stored as clear text.

The solution? Store the password as a SHA-1 hash. Nobody would want to store password as clear-text anyway.

So, issue solved!

You may run slapd in debugging mode, that is slapd(8) -dacl
