ldap user auth doesn't work after update to actual version

[vmpr]

Hi everyone, I have a strange problem. I updated our XO from sources last week, and now LDAP auth is not working anymore

Interesting part is: when I try it on CLI it works

/opt/xo/xo-builds/xen-orchestra-202507030450/packages/xo-server-auth-ldap/dist# node test-cli.js
? URI ldap://company.zone

? Base DC=company,DC=zone
? fill optional Credentials? Yes
? Credentials > dn user@company.zone
? Credentials > password XXX
? fill optional User filter? Yes
? User filter (sAMAccountName={{name}})
? ID attribute (sAMAccountName={{name}})
? fill optional Synchronize groups? No

But in the web interface with the same configuration, I get an error

Code: -32000

}

any ideas what could be the problem?

Hi,

Can you double check the case for the base and not use caps? (like dc instead of DC)

[vmpr]

@olivierlambert sadly that didn't help

[olivierlambert]

All in all, it's likely related to the fix we did on it "recently" (like 1 or 2 months ago tops).

Is anyone from XO team could assist? Maybe @pdonias since I think you fixed it? (I can be mistaken though)
