Sftpgo external authentication using LDAP

[Knkkyl]

I am using sftpgo version 2.5.3 . User is authenticated successfully using external LDAP authentication. LDAP server sending response code as 200 and response body as empty to sftpgo but it is giving "invalid credentials" error. As per sftpgo documentation , we can pass empty response body of we don't want to update user details in database. Also if I am passing username & permissions in response body , then it is overwriting database, hence if admin does any change for any user , then that changes will be removed once user logout and login.
