LDAP login execution timeout

Added by M K about 8 years ago

Hi All

We have started experiencing issues while logging into local redmine server hosted on Win server 2012R2 with apache24. The redmine is configured to use LDAP authentication. The login page return 500 error when using Active Directory credentials, but no issues when using local redmine admin account.

The error on the browser:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /login.
Reason: Error reading from remote server

Our Redmine Environment:
Redmine version 3.2.0.stable
Ruby version 2.2.4-p230 (2015-12-16) [x64-mingw32]
Rails version 4.2.5
Environment production
Database adapter Mysql2
SCM:

Redmine plugins:
no plugin installed

We are also using LDAP with Active Directory login accounts.

I also have the same issue, please see here:

LDAP login execution expired

Seems to be a common issue now, with multiple reports e.g. also here:

Internal Error on LDAP Auth

Yet no one has been able to suggest any cause or resolution. Anyone able to provide some advice for us? Will raising an issue help?

Thanks,

Ben

Did you try to increase expire time?

RE: LDAP login execution timeout - Added by Ben Earner about 7 years ago

I set the timeout to 60 seconds. It seems to throw the error almost instantaneously from my experience. If I login with a local account, it works. Then the same LDAP account which was failing will then begin working.

One thing I'm trying now is to use a dynamic bind to see if that prevents the error (RedmineLDAP), I was using a dedicated user before for the initial bind.

RE: LDAP login execution timeout - Added by M K about 7 years ago

The issue had gone I changed the host field in the LDAP settings to the domain controller name. It was just a domain name below.
Before - Domain.Lan
After - DC01.Domain.Lan

This fixed the issue.

Thanks, I will try that too.

Thanks changing the domain controller name worked for me.
