LDAP Authentication Issue: QNAP Active Directory - "Invalid username or password"

[kayzer699 1]

Hello Emby Community,

I am having trouble configuring the LDAP plugin on my QNAP NAS using the built-in Active Directory (Domain Controller). Despite various configuration attempts, I consistently receive the "Invalid username or password" error in Emby.

Environment:

• Server: QNAP NAS (QTS 5.x)

• LDAP Source: QNAP Active Directory Controller

• User Status: The user (asli) can successfully log in to the QNAP Web UI. Application permissions (Desktop/File Station) are granted.

Current LDAP Plugin Settings in Emby:

• LDAP Server Address: 127.0.0.1 (Also tried local IP)

• Port: 389

• Bind DN: cn=administrator,cn=Users,dc=koken,dc=home

• Bind Credentials: (Verified admin password)

• User Search Base: dc=koken,dc=home

• User Search Filter: (sAMAccountName={0}) (Also tried (&(CN={0})))

The Issue: When I attempt to log in with the username asli, Emby returns an authentication error. I have tried logging in as asli and KOKEN\asli, but neither works.

The user exists in the cn=Users container on the QNAP Domain Controller. I have already enabled "Allow LDAP authentication" in the Emby User settings.

What could be missing in my DN syntax or search filter for a QNAP-based AD setup?

Any help would be appreciated.
