HBAC Service Groups

HBAC service groups can contain any number of individual services,
or "members". Every group must have a description.

EXAMPLES:

 Add a new HBAC service group:
   ipa hbacsvcgroup-add --desc="login services" login

 Add members to an HBAC service group:
   ipa hbacsvcgroup-add-member --hbacsvcs=sshd,login login

 Display information about a named group:
   ipa hbacsvcgroup-show login

 Add a new group to the "login" group:
   ipa hbacsvcgroup-add --desc="switch users" login
   ipa hbacsvcgroup-add-member --hbacsvcs=su,su-l login

 Delete an HBAC service group:
   ipa hbacsvcgroup-del login
