We encountered such a problem. When we call for \\<server>\<share> the
system cannot authenticate currently logged in user. Enviroment is clientless

The first suggestion was check cifsctxs.cfg. But it seems ok, all the
contexts where users are located was on place. Besides this problem relates
not to all users. There are 2 particular users from the same container that
behave differently. It doesn't look like context problem.
Are we missing something?

Any help will be appreciated
