SELinux is preventing /usr/bin/xauth from 'read' accesses on the directory /etc/samba.

*****  Plugin leaks (50.5 confidence) suggests  ******************************

If you want to ignore xauth trying to read access the samba directory, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
# grep /usr/bin/xauth /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (50.5 confidence) suggests  ***************************

If you believe that xauth should be allowed read access on the samba directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep xauth /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

> What were you doing when you saw this avc?

Mr daniel,I am new in linux and bugzilla too so,at the time of sending bug reports I could not sent all the details and for that I am very sorry for that.

Now I am sending all the details read it minutely.-----

       I sent the deatails to understand it very clearly.The engineers of Red hat/Fedora or the developer of this software which is responsible for this bug are requested to solve the problem as soon as possible.I am new user of linux(Fedora)so,I did not know how to send bug report and how to see a bug report.

       After downloading fedora 15 (http://torrent.fedoraproject.org/------->Fedora 15------->Fedora-15-i386-DVD.torrent)I installed Fedora 15 dvd with Kde,Gnome and Xfce desktop,I took update 1 by 1 and in that time I got the first bug but can not remember particularly which software made the first bug.Total I got 2 bugs.I got the 2nd bug at the time of clamav auto configure.

        For these 2 bugs my system got crashed.When I installed Fedora 15 in my desktop computer,to log in my desktop computer I was asked to enter passpharase in my computer and after paspharase I had to enter user(standard) password/user (admin)password/root password and I have 2 users but after getting these 2 bugs I could see that I do not need to enter any password to login my desktop and after shut down when I am trying to start my desktop computer,I need only passphrase to login my desktop and can see the last user in the user list got autometically login without any password.

       After entering in last user desktop if I need to start another user session then I need to logout from this user and loin desktop by other user and in that time I can see that particular password for the particular user not working means some times I can see the particular password of the 1st user if I enter in 1st user field I am getting the 2nd user desktop so,I think those bugs have destroyed my password system so,please you are requested to solve the problem fast because my system is behaving like a mad.All are requested to read these paragraph carefully to know the problem clearly.

To understand this bug you have to see my first bug report id=722747,In my 1st bug report Mr.Daniel Walsh--you have written that your working on it.

So,My first bug id number is 722747  and  2nd bug id number is 730185.

Mr daniel and all the engineers of the fedor please tell me what should I do now?means to reinstall fedora 15 or to wait for new updates.

Again I am telling sory because a number of times i sent same bugs because I did not know how to send bugs because I was the user of Microsoft Operating System and there is no bug reporting system in Microsoft,all will be done in microsoft autometically.

I don't think either of these bugs is related to you not being able to login.
