Describe the Scenario

Hi Dan,
I am currently trying to connect my Bookstack server (on Xampp) to my active directory but it is not working and I can't figure out why. I work in a large company, so I need to set up LDAP based authentication. I want an authenticated user to have direct access to boockstack without needing to authenticate through the sso link.

I followed your video on ldpa but when I use it, it doesn't work, the problem would come from the Active Directory consultation. Here is the error I get:

Here is the AD part of my configuration file:

Exact BookStack Version

v23.05.1

Hi @TomBachelot, typically either BookStack is failing to reach the LDAP system, or the TLS is failing when attempted to be upgraded by the host system.

Does the result change when you change LDAP_START_TLS to true?
Otherwise, are you confident the LDAP system in contactable on the configured address?

@ssddanbrown, Yes the result does change when I change LDAP_START_TLS to true but I still get an error unfortunately:

Otherwise, yes I'm sure that the LDAP system can be reached on the configured address.

I can provide you the Stack Trace if you want ?

@TomBachelot commented on GitHub (May 15, 2023): @ssddanbrown, Yes the result does change when I change LDAP_START_TLS to true but I still get an error unfortunately:  Otherwise, yes I'm sure that the LDAP system can be reached on the configured address. I can provide you the Stack Trace if you want ?

I don't think the BookStack stack trace will provide any extra context in this case.

Have you done anything to check the connection from this specific host system?
Since you're on a Windows server, you may be able to do something like this via PowerShell:

Test-NetConnection -ComputerName srv-dc01-2019.gesconseils.local -Port 389

@ssddanbrown, thanks for helping me because im very in need !

I tried the PowerShell command you gave me and it seems to be ok :

but I made a typing error in the server address. Now it's working a bit more, here is what I got:

I tried the ldap auth method without using the LDPA_START_TLS and i've got no errors but without knowing why it says "this informations does not match any account"

And when I try with the LDAP_START_TLS=true , i have an issue :

Okay, leave LDAP_START_TLS as false unless you specifically need tls since it looks like your server does not actively support it using the current connection details.

I tried the ldap auth method without using the LDPA_START_TLS and i've got no errors but without knowing why it says "this informations does not match any account"

This usually indicates that the password is incorrect or, more likely, no matching user is coming back in the LDAP search BookStack is performing.

Are you sure your LDAP_USER_FILTER value is correct? For AD systems I usually expect to see something along the lines of LDAP_USER_FILTER=(&(sAMAccountName=${user})) instead.

The only other immediately suspicious element of your config is the LDAP_BASE_DN, it looks quite specific. Remember that all searches will be performed with this DN as a base. Your LDAP_DN is also outside of this base which could maybe cause issues (but I'm not so sure about this, might depend on the LDAP system). Start with the LDAP_USER_FILTER before attempting to alter anything here.

Since there's been no further follow up I'll close this off.
