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 (using Bash
brace expansion):
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 (using Bash brace expansion):
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"
""")
