sshd not filtering correctly with match group
sshd bz#1315 negative searches without a positive search do not work.
A match command will only work if the search string contains at least one term that will match positively.
Add a positive match group to the line.
For example:Match Group "term1,term2,term3..." will only work if at least one of termN is not prepended by !. Thus,
Match Group "!VAS,!Accounting" will not work, but Match Group "!VAS,!Accounting,Linux-users" works .
Note no ! in front of Linux-users making it a positive search
