[ZendTo] News — Microsoft enforcing LDAPS for AD servers

[Karl Bundy]

I also am running RedHat7/CentOS7 and having the same issue.  Nothing seems to output any helpful logs to help troubleshoot the source of the issue (cert issue, missing packages, etc.)  Any suggestions would be appreciated!

Thanks,

Karl Bundy

Running on Redhat 7

Made changes to /etc/openldap/ldap.conf
Made changes to preferences.php
Get login error
	LDAP Error
	Check User: Unable to connect to any of the authentication servers; could not authenticate user. Please notify the system administrator.
	Authentication Error
	The username or password was incorrect.
Found I did not have gnutls installed, and thought it might be required. Not sure how else to test...
Maybe a list of packages that might be required?

Microsoft are about to enforce the use of LDAPS (removing unencrypted LDAP) when checking user credentials against an AD server.

This needs a couple of minor changes to your ZendTo server.

I have written up some simple instructions here
    https://zend.to/activedirectory.php
which certainly appear to work for me.

I strongly advise you make the changes and test the resulting service before Microsoft release the patch that enforces the need for this. It should cause no harm except to improve the security of communications between ZendTo and your AD server.

Any comments / problems / questions, please do let me know straightaway!

Cheers,

Jules
