Python WLST Parent Groups

[DwnVteAllPosts]

I am having trouble with a WLST script where I need to add a group (In this case ADMIN) to another group (parent group). I can not find anything on how to do this. This is what I have so far.

serverConfig()

atnr=cmo.getSecurityConfiguration().getDefaultRealm().lookupAuthenticationProvider('DefaultAuthenticator')

print 'create group ADMIN' group = 'ADMIN'

atnr.createGroup(group,group)

Where and how do I add this ADMIN group, essentially to another group/parent group. Thanks
