Hi All, I think here we have a confusion between immutable attributes and Unique attributes.
*Immutable Attributes* : Will not change over the time (Using this attribute can track the identity over the time) *Unique Attribute* : this is unique to the system but can be changed over the time and this can be tracked with a immutable attribute. With the new design UserID would be the Immutable attribute (But read only identity stores this can be changed) And user name is a unique attribute. So in new implementation also isUserExist should return true if there is a user with given user name. And this is applicable to all unique attributes.
