Group to Group Delegation 

A permission enables fine-grained delegation of permissions. Access Control 

Rules, or instructions (ACIs), grant permission to permissions to perform 

given tasks such as adding a user, modifying a group, etc. 

Group to Group Delegations grants the members of one group to update a set 

of attributes of members of another group. 

EXAMPLES: 

Add a delegation rule to allow managers to edit employee's addresses: 

   ipa delegation-add --attrs=street --group=managers --membergroup=employees "managers edit employees' street" 

When managing the list of attributes you need to include all attributes 

in the list, including existing ones. Add postalCode to the list: 

   ipa delegation-mod --attrs=street --attrs=postalCode --group=managers --membergroup=employees "managers edit employees' street" 

Display our updated rule: 

   ipa delegation-show "managers edit employees' street" 

Delete a rule: 

   ipa delegation-del "managers edit employees' street"
