Contains the disabled status of the Identity Manager user. It is set to a value that is logically true if the account is disabled. In the memory model, it is either a Boolean object or the string true or false. When accessed through forms, you can assume it is a string.
You can modify this attribute to enable or disable the Identity Manager user, although it is more common to use the global.disable. (Prepending global. to a variable name ensures that the system applies the value of that variable to all resources that recognize the variable, including Identity Manager.)
Once this value becomes true, the user cannot log in to the Identity Manager user interface.
