The invalid option is 'mjt', it isn't a number, you are possibly
mistaking it for the rfc2307 attribute 'uid' which is a name. The 'uid'
in this instance is the users Unix ID e.g.
rowland at devstation:~$ wbinfo -U 11104

It as been like that since 4.0.0 at least.

If you wish to change it, I would expect that patches would be readily
