SELinux and Likewise Open Issue

[Mr. Paul M. Whitney]

Hello everyone, I am having an issue with SELinux and Likewise Open.  I have managed to "successfully" install the product by setting SELinux to permissive mode and have successfully  joined it to a domain.  I have also used my AD credentials successfully. 

After rebooting and SELinux in enforced mode, I am getting the below SELinux AVC denial.  I "think" it may be because the .lsassd file is labeled with a generic "var_lib_t" and perhaps it needs to be something like "likewise_var_lib_t".  I don't know and this is probably demonstrating my ignorance with SELinux.  I am running into dead ends or unrelated info on Google, Red KB, and several people's blogs.

Can someone please tell me how to overcome this denial with SELinux in enforce mode?


Summary:

SELinux is preventing dbus-daemon (system_dbusd_t) "write" to .lsassd
(var_lib_t).

Detailed Description:

SELinux is preventing dbus-daemon (system_dbusd_t) "write" to .lsassd
(var_lib_t). The SELinux type var_lib_t, is a generic type for all files in the
directory and very few processes (SELinux Domains) are allowed to write to this
SELinux type. This type of denial usual indicates a mislabeled file. By default
a file created in a directory has the gets the context of the parent directory,
but SELinux policy has rules about the creation of directories, that say if a
process running in one SELinux Domain (D1) creates a file in a directory with a
particular SELinux File Context (F1) the file gets a different File Context
(F2). The policy usually allows the SELinux Domain (D1) the ability to write,
unlink, and append on (F2). But if for some reason a file (.lsassd) was created
with the wrong context, this domain will be denied. The usual solution to this
problem is to reset the file context on the target file, restorecon -v
'.lsassd'. If the file context does not change from var_lib_t, then this is
probably a bug in policy. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against the selinux-policy
package. If it does change, you can try your application again to see if it
works. The file context could have been mislabeled by editing the file or moving
the file from a different directory, if the file keeps getting mislabeled, check
the init scripts to see if they are doing something to mislabel the file.

Allowing Access:

You can attempt to fix file context by executing restorecon -v '.lsassd'

The following command will allow this access:

restorecon '.lsassd'
