Severity: 3-Major


For the Application editor user role, REST PUT calls to modify LTM Node parameter 'session' to "user-enabled" or "user-disabled" will fail randomly with the error response " seteuid error 1: Operation not permitted ".


Intermittent failures to modify LTM->Node->session will fail, and subsequent operations will succeed.


1. User role is Application Editor. 2. REST PUT method is used to modify the LTM->Node->session 3. Only the PUT operation for modifying LTM->Node->session tends to return the error response. 4. No other LTM config object was facing this issue.


Using PATCH instead of PUT to modify /mgmt/tm/ltm/node "session" attribute will stop the intermittent failures observed with the PUT operation.
