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"
