[Samba] Domain Join

[Sandbox]

Hello,


I would like to join my samba4 to my existing samba4 DC.
The existing samba4 is a fresh, default install, every tests worked fine,
provisioned like this:
samba-tool domain provision --realm=test.domain.lan --domain=test.domain
--host-ip=10.48.16.150 --adminpass='password' --dns-backend=BIND9_DLZ
--ldapadminpass='password' --server-role=dc --use-xattrs=yes --use-rfc2307
--function-level=2008_R2

When I run:  samba-tool domain join test.domain.lan DC -UAdministrator
--realm=test.domain.lan --dns-backend=BIND9_DLZ

I got this error message when i wrote the correct LDAP password, if I wrote
the incorrect password it just keep asking for the password.

Finding a writeable DC for domain 'test.domain.lan'
Found DC domainc01.test.domain.lan
Password for [WORKGROUP\Administrator]:
Failed to bind - LDAP error 49 LDAP_INVALID_CREDENTIALS -

Did I miss someting?
