SSH Login, using 'tester' account (in Adminstrators group) to the Cygwin sshd server fails from a client machine which has ~/.ssh/id_rsa keys available.
Login from the same client, without the id_rsa keys is successful. SSH locally (on cygwin box) is also successful. Comparison of the sshd logs (debugging enabled) of a good vs failure login shows that when id_rsa is enabled on the client, the following in the failure case: debug1: temporarily_use_uid: 1000/513 (e=18/544) seteuid 1000: Operation not permitted This seem to be related to a permission related problem, but cygcheck_output though shows the 'tester' user is member of Administrators group. What I am I missing? Thanks, Novice Cygwin user
