[root at myname crm]# cd ..
[root at myname run]# ls -ld crm
drwxr-x--- 2 hacluster haclient 200 Jan  4 10:31 crm
[root at myname run]# ls -l crm
total 0
srwxrwxrwx 1 hacluster root 0 Jan  4 10:31 attrd
srwxrwxrwx 1 hacluster root 0 Jan  4 10:31 cib_callback
srwxrwxrwx 1 hacluster root 0 Jan  4 10:31 cib_ro

If I change the crm directory permissions from 750 to 755 then
things work.  Should that be needed?

Looking at the spec file I find the following:
%dir %attr (750, %{uname}, %{gname}) %{_var}/run/crm

Adding the user to the haclient group works but then the user has
full write access which isn't what is wanted.
