Authenticate against LDAP
« on: September 14, 2010, 08:17:27 PM »
I try to authenticate users from Wireless AP against LDAP on SME 8

in config menu of wireless device I have one option to test the configuration
if I put there "testuser" account and hit the "test" button
I receive back all data sent by LDAP and everything seems ok
but when I try to use this settings direct on authentication on server /var/log/messages I see one error
and authentication fail

slap_global_control: unrecognized control: 1.3.6.1.4.1.42.2.27.8.5.1

on openldap site is associated with "not loaded module" or not compiled for password
http://www.openldap.org/lists/openldap-software/200606/msg00021.html

I think I made something wrong and I ask for second opinion

the full output in mesage is as follow

Code: [Select]

Looks like your not using TLS or SSL for the LDAP connection. LDAP ACL allow clear text consultation of non sensible inforamtions (that's why the test display some data), but in order to authenticate against LDAP from a host other than localhost, you need to enable SSL or TLS.

That mean I need to import server certificate into device - most probably
and use the port 636?

Depends on your device. Port 636 is usually for LDAP over SSL. But you can also use the standard port 389 with TLS. In any case, yes, you'll probably need to import your server certificate into the device.
