Connect to Synology Directory Server using LDAP plugin

[gigasnow 2]

Hi, the synology directory server needs gss-api on port 389 or ssl with specified username and credentials on port 636 to login. I have successfully login using LDAP Admin through ssl, but when I turned to the emby LDAP configuration, I failed with the log message: ‘comment: AcceptSecurityContext error, data 52e, v1db1’, which means the credential is wrong.

I believe the reason is that the Synology directory server only allows username@domain to login. May I ask how to set the specified username in Emby LDAP, or how to implement it in the Bind DN?

Many thanks!

Hi, the username corresponds to the username in your emby server. I've never tried to set this up with Synology directory server but does this help?

Thanks for your reply! There are two directory packages in Synology, this article is talking about LDAP server, while the one I used is Synology Directory Server. 
It only allows username@domain:credential to login, while using ssl simple authentication on port 636. But in the LDAP plugin of Emby, the username is fixed in the Bind DN, and can’t be customized. 
I tried to add uid=username@domain and E=username@domain in the Bind DN, but both didn’t work. 
If the plugin allowed me to configure just as the LDAP admin shown in the picture, it would work.

It is definitely the Synology's problem. I switched to Windows AD, and used administrator@domain as Bind DN. It worked.

Thanks for the update.
