Moodle Ldap problem

[anne1]

We have moodle sitting on a Ubuntu server and using LDAp to authenticate the users to AD. It's worked fine since November then at 3pm todau stopped letting us login with error
LDAP-module cannot connect to any servers: Server: 'ldap://servername.domainnameConnection: 'Resource id #61' Bind result: ''

We haven't changed anything. Most stuff on the web says it's a bind user issue, but why would it change?

How can I check the binding settings when I can't get into Moodle?

Is there a way to get into moodle from a back door on ubuntu?

I'm a moodle and ubuntu newbie, so all help gtreatly appreciated.

Thanks

A bind result is usually a username/ password issue

Sorry I cant be of anymore help but i would check user expiration and check there have been no password changes etc

Password expirations also a cause of this, that you never realise until its to late.

The Moodle backdoor would be the admin user setup totally independently of LDAP and AD - surely you have one for the initial setup to take place. That'll be the way back in.

Yup, check the bind user/password. Had an issue with this when we updated all our admin passwords, and forget to change it in the moodle config.
