This looks like a bug in the server itself. This line:

  https://github.com/openmicroscopy/openmicroscopy/blob/dev_4_3/components/server/src/ome/logic/LdapImpl.java#L474

doesn't strip off the ":bean:" prefix as is done in the other beans, e.g.

  https://github.com/openmicroscopy/openmicroscopy/blob/dev_4_3/components/server/src/ome/security/auth/QueryNewUserGroupBean.java#L46

You can try to rename your bean :bean:hyHcNewUserGroupBean and see if that works. And I'll look into fixing this as soon as possible.

Thanks for hanging in there!
