So,

Im am trying to do just this but failing,

So rather than,

ipa sudorule-add-allow-command --sudocmds "/bin/su - banner" 

then,

ipa sudorule-add-allow-command --sudocmds "/bin/sudo  -i banner"

Note you can also allow sudo -i which gives you an interactive shell
just like su - would, but you can control sudo configuration centrally.
