Self-service Permissions

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.

A Self-service permission defines what an object can change in its own entry.


EXAMPLES:

 Add a self-service rule to allow users to manage their address:
   ipa selfservice-add --permissions=write --attrs=street,postalCode,l,c,st "Users manage their own address"

 When managing the list of attributes you need to include all attributes
 in the list, including existing ones. Add telephoneNumber to the list:
   ipa selfservice-mod --attrs=street,postalCode,l,c,st,telephoneNumber "Users manage their own address"

 Display our updated rule:
   ipa selfservice-show "Users manage their own address"

 Delete a rule:
   ipa selfservice-del "Users manage their own address"
""")
