Edit a custom RADIUS attribute if you need to change its name, value, or mapping to an identity attribute. For example, you might edit a custom RADIUS user attribute definition called UserGroup to no longer map it to an identity attribute. If you modify the name or number of the attribute, you must modify the RADIUS attribute definition in the dictionary. For instructions, see Add a RADIUS Attribute Definition to a Dictionary.
In the Security Console, click RADIUS > RADIUS User Attribute Definitions > Manage Existing.
