How do you convert a non-LDAP user to using LDAP?

If you want to take an existing (non-LDAP) user and 'upgrade' them to using LDAP you can do so using the OMERO command line tool:

bin/omero ldap setdn

while logged in as an administrator. The process is also reversible so that the OMERO password for a user rather than the LDAP password will be used. See the caveat in the setdn help output below:

    usage: bin/omero ldap setdn [-h] username dn

    Set DN for user (admins only)

    Once the DN is set for a user, the password set via OMERO is
    ignored, and any attempt to change it will result in an error. When
    you remove the DN, the previous password will be in effect, but if the
    user never had a password, one will need to be set!

    Positional Arguments:
      username            User's OMERO login name
      dn                  User's LDAP distinguished name. If empty, LDAP will be disabled for the user

    Optional Arguments:
      In addition to any higher level options
