#2368 ipa-client should not require SELinux be enabled.
Closed: Fixed None Opened 10 years ago by jraquino.

The yum installation of ipa-client does not ever install policycoreutils as a dependency which causes ipa-client-install to fail.

Traceback (most recent call last):
File "/usr/sbin/ipa-client-install", line 1292, in <module>
File "/usr/sbin/ipa-client-install", line 1279, in main
rval = install(options, env, fstore, statestore)

We should probably just make restorecon execution optional in ipa-client

We should check to see if SELinux is enabled by running /usr/sbin/selinuxenabled (if the binary exists) before running restorecon.

Without policycoreutils sshd restart fails during uninstallation:

Traceback (most recent call last):
File "/usr/sbin/ipa-client-install", line 1534, in <module>
File "/usr/sbin/ipa-client-install", line 1514, in main
return uninstall(options, env)

ipautil.run(["/sbin/service", self.service_name, "restart", instance_name],
File "/usr/lib/python2.6/site-packages/ipapython/ipautil.py", line 291, in
raise CalledProcessError(p.returncode, args)
subprocess.CalledProcessError: Command '/sbin/service sshd restart ' returned
non-zero exit status 1

It was also reported that during install getent passwd admin fails but that may be a red herring.

JR, to get the openssh guys to look into possibly correcting their package as well to work without policycoreutils installed I need to gather some additional information.

What is the SELinux context of sshd_config? Can you see if the file has been changed (rpm -V openssh-server)?

I think we need to:

- warn when restorecon is not found and selinux is enabled
- don't consider failing to start sshd as fatal

The getent passwd admin not found was not a red herring, it is caused by this:

type=AVC msg=audit(1337290408.174:15432): avc: denied { read } for pid=15428 comm="sssd_be" name="krb5.keytab" dev=dm-1 ino=137005 scontext=system_u:system_r:sssd_t:s0 tcontext=unconfined_u:object_r:var_lib_t:s0 tclass=file

sssd is running but not usable.
