pgadmin4 container deployment with ldap-authentication

Hi,

i am trying to get pgadmin4 running in server-mode as a
docker-container. So i pulled the image and after i tried out the image
a little bit, i tried to use ldap-authentication.

Unfortunately, i didn't get it running as expected. I am not able to
authenticate against my samba 4-domain. This is how i tried to launch
the container:

docker run -p 8280:80
    -e "PGADMIN_DEFAULT_EMAIL=<emailAddress>"
    -e "PGADMIN_DEFAULT_PASSWORD=<password>"
    -e "AUTHENTICATION_SOURCES=['ldap']"
    -e "LDAP_AUTO_CREATE_USER=True"
    -e "LDAP_SERVER_URI='ldaps://<domaincontroller>:636'"
    -e "LDAP_BASE_DN='cn=Users,dc=mydomain,dc=local'"
    -e "LDAP_BIND_USER='cn=User1,cn=Users,dc=mydomain,dc=local'"
    -e "LDAP_BIND_PASSWORD=<BindDNPassword>"
    -e "LDAP_CA_CERT_FILE='/etc/ssl/certs/myca.pem'"
    -e "LDAP_CERT_FILE='/etc/ssl/certs/my.cert.pem'"
    -e "LDAP_KEY_FILE='/etc/ssl/private/my.key.pem'"
    -d dpage/pgadmin4

I am using the container behind a reverse-proxy on nginx (debian
buster), for the first try via http. The authentication with the given
user PGADMIN_DEFAULT_EMAIL works as expected but ldap-authentication
results in an error-message "Specified user does not exist".

Am i using the environment-parameters for ldap-authentication correctly?
May a reverse-proxy over https help to get ldaps working?
