Ldap connection in version 25

Hi,
in version 24, i was able to connect to AD through ldap, and search AD users in the ‘users’ tab of keycloak. Now i am trying to do same thing on keycloak 25, ‘users’ tab just doesnt search anything (yes it actually doesnt search because request ends instantly, it is not something like search filter is wrong).
User federation configs are exactly same as configs of 24 and ldap connection test and authentication tests are successful too.
I am doing all of these on development mode.

Changing search scope from ‘one level’ to ‘sub tree’ solved the issue.
However, in version 24, ‘one level’ works too. There is a conflict honestly.
