ACLs and Locking
As explained previously, locking allows you to control access at the individual user level, while ACLs allow you to control access by groups of users. Following are guidelines to keep in mind as you use ACLs with locking:
To lock an element, you must be the member of the ACL that is assigned for Write access to that element.
To lock a Java or C service within a folder, you must be the member of the ACL that is assigned for Write access for
all Java or C services in that folder. This is because locking and unlocking actions for Java/C services are at the folder level. For details, see
Guidelines for Locking Java and C/C++
Services.
To edit ACL permissions for an element, you must lock the element (except for packages and folders, which cannot be locked).
