Hello Joey I try to use Ssh.authorizedKey (User "com-sixs") sshKeyPubComSixs on a system where the account are available in a ldap. On this system the group is different from the user name name -> grp-name So I end up with this error message chown: invalid group: ‘com-sixs:com-sixs’ sixs3.exp.synchrotron-soleil.fr com-sixs has authorized_keys ... failed so my questions are. - Is it mandatory to have a user and the identical group on a unix system ? - Can we add a Group parameter to the authorizedKey property ? thanks for your help Fred
