Re: Strict policy on FC6 and F7

Hi Louis,
do not loose your time with login.te module. It does not work, or at least it
does not allow login.

I could not fix the problem for myself but managed to find that my initial
problem with firefox is still not solved in f7 even with the latest policy.

So I am still looking for a solution of the firefox problem.

regards
Hal
