| 28 | @discussion This class provides an ACL security scheme. |
---|
| 29 | This can manage rights to 'run' applications, and limit certain features within an application. |
---|
| 30 | It is also used for granting a user "membership" to a group, or making a user have the security equivilance of another user. |
---|
| 31 | It is also used for granting a user or group rights to various records, such as todo or calendar items of another user. |
---|

| 33 | @example $acl = CreateObject('phpgwapi.acl',5); // 5 is the user id |
---|
| 34 | @example $acl = CreateObject('phpgwapi.acl',10); // 10 is the user id |
