New Users in AD not showing up in compute nodes

Hi Team ,
I am running a test BRIGHT Cluster using VMWare VMs . The cluster nodes are integrated to Windows Active Directory using realm . Whenever I create a new user in Windows AD , these new users are not showing up in Compute nodes and secondary head node . I had to run realm leave command and then run real join command in secondary head node to fix the issue. I will have to do the same steps in compute nodes also . Could you please let me know how can I fix this permanently .
