LDAP protocol in Linux Docker

[istretyakov]

Hi!

I try to send LDAP request from Docker container using System.DirectoryServices.Protocols 5.0.0 on .NET 5.0.
In Windows-case i get response that server is unavailable. It's right. This response shows that request was sent. In other environment (work) i get users. With Docker and without Docker, on Windows.
But in Linux-case (Docker) each time i have this exception: The LDAP server returned an unknown error. ErrorCode -1. I can write not existed server and i will get this exception. It means that doesn't work. And i added installing libldap-2.4-2 in Dockerfile.
One code, different reactions.

Windows:

Linux:

try this

AuthType = System.DirectoryServices.Protocols.AuthType.Basic

We also had many problems with LDAP on Linux using System.DirectoryServices.Protocols.*. In the end, only one thing helped: The migration to Novell.Directory.Ldap.NETStandard. This allowed us to reliably use LDAP under Linux 👍 .
