LDAP: Error Found 'Test User' but this user has no groups... about scot

[toddbruner]

Do you have a "Test User" in you LDAP and if so is that "Test User" a member of any groups? I think that the error is saying, I was able to find 'Test User' in LDAP, but I didn't get back any groups. Reasons for this include invalid User ID attribute, invalid membership attribute, or "Test User" is not in any groups.

We will probably need to know more about your LDAP setup to debug this one.

As you can see, I am using objectClasses posixAccount, posixGroup to provide LDAP servers to our Linux machines. Is there another option I can enter for the “Membership Attr” field instead of “memberOf”? Since, my LDAP server is not using the OpenLDAP ‘memberof’ overlay? Below are the values during SCOT LDAP setup:

LDAP Server: ldaps://ht-ldap-0.it.anl.gov
Base Domain: dc=it,dc=anl,dc=gov
User ID Attribute: uid
Membership Attr: memberOf
Bind DN: cn=cfm,ou=People,dc=it,dc=anl,dc=gov
Bind Password: password
Test User: cfm

Thank you for helping me troubleshoot OpenLDAP integration.

Jose

After changing OpenLDAP to support rfc2703bis schema and using the memberOf overlay, finally was able to successfully validate against SCOT LDAP auth using the admin account. How do I use LDAP credentials for the SCOT HTTP basic authentication? Do I use the username@localdomain syntax?

We have an update I need to apply that should help with your original problem. I'm glad you have got it to work though.

As for your second question, I apologize if I am not understanding the question, but SCOT looks for a session cookie, if it is not present, then you will get 401 which will prompt the browser to provide a basic auth popup. There you will enter username / password combination. I've never tried "username@domain" as a login, but it might work. It should be passed on to LDAP and if it can parse it, then we should be fine.

Hope that helps...
