[JENKINS-72732] ActiveDirectory authentication error with german umlaut in user DN

Description

New: Hi. I am using Ldap plugin to authenticate to ActiveDirectory, and all users not having german umlaut like "ÄÖÜ" in their user-dn can login fine: For example: DN: CN=Franz Tester,OU=Users,DC=example,DC=com sAMAccountName: tester201 ( please see Picture1 too) All users, with ÜÖÄ in its surname or lastname get an authentication error. DN:: base64 encoded string sAMAccountName: tester202 ( please see Picture2 too) I know, it is recommended not to use german umlaut in the DN, but my company has configured it like this, and i cannot change it. I am not a developer, so i cannot help to fix this problem, but i hope someone is here to help me. I have tested several configurations with different ldap queries and changed my password to something simple, but nothing works. So i have no further idea and think, it could be a problem with the plugin code to not decode the DN correctly, maybe. Thank's in advance for your help!
