Authentification failed on account not in adm group

[gchu]

I created AdminGrp which contains VNCAdmin account which allow full access. But one machine worked, the other I have to add VNCAdmin account to Administrator group. Otherwise it would not connect.

Any idea? I am using 1.0.8.2
Thanks.
Greg
