Still, I would like to see the session log. Because since 5.0.6 you should not see any "lookup user groups" errors.

Hi,
thanks for the reply.
I have solved the problem when i have take a look at SCP configuration file that is written by WinSCP.
When i have disabled the checkbox under SCP option, i have notice that the setting's name was
LookupUserGroups2=1

so i have added this line of code to my app
sessionOptions.AddRawSettings("LookupUserGroups2", "1");

and all works fine.
Thanks to all.
Stefano

Please set Session.SessionLogFile and attach the log file to this thread.

hi,
i have a problem with a SCP server that i can solve only if i disable "lookup user groups" in WinSCP Client.
But using .NET Dll in my client, i cannot reach to find any options to do that programmatically.
What can i do ??
Thanks in advance
Stefano
