In rest if I, for a standard user, use
"/services/data/v28.0/sobjects/User/"User ID"/Password"
to check whether logged in user password is expired or not (testing in REST explorer Workbench).
When I give 18 digits ID in user id I get an error -Error code- INSUFFICIENT ACCESS MESSAGE- you do not have permission to view the record.
However If I use 15 digits ID I do not get any error, - isExpired=true"
Is someone else also experiencing this weird behavior ?
