  • It would be helpful if you provided a few more details up front. Vague questions like this are a good way to get down-voted.

It means it couldn't connect to the LDAP instance you specified.

  • Make sure your configuration under Administer >> Site Configuration >> LDAP Integration is correct. You can refer to the documentation here.
  • Try connecting with an LDAP client like JXplorer to validate that your LDAP instance is up an running at the host and port you think it is.

If you want a better answer you'll have to provide more details.

  • @BenV: What information would be of use? I've looked at 100s of pages related to it, tried lots of stuff. If you read the comments on the page you linked to, you'll notice a common theme... the documentation is superbad, if not plain wrong. I've tried coding a basic LDAP connection by hand in PHP, but couldn't get it to work (as a control test)... here's the post on that: stackoverflow.com/questions/3993128/… happy to answer ANY and All questions, just can't believe someone would take the time to code something like this and not have feedback test.

  • @blunders: From tinyurl.com/so-hints: What did you expect it to do? What are you trying to accomplish? What have you already tried? What happened in those attempts? Be detailed: in particular, if something didn't work, don't just state that: tell us how it failed. If it threw an exception, what was the exception? (Don't just give the type - give the error message and say which line threw it. If there's a nested exception, post that too.)

I'm not sure if this is the same problem you're having, but you might look at this: http://drupal.org/node/99009

  • @Adam Thompson: Thanks, and yes, I've seen that page. In some cases, OpenLDAP 2.3+ (I believe) it requires a SSL-CERT by default, "TLS_REQCERT never" turns that requirement off. I've tried that, but received the same error. Do believe both Apache and PHP are working right, but super hard to tell... :-)
