Lock request failed: 401 Authorization Required

Runnig Software PB10.2.0 Build 8100
Subversion 1.2.3
Pusk Ok version 1.2.0_050808

I had problem with locking files, on some machine and users.
We used Subversion 1.2.1 first (same problem, then we uppgraded, it didn't
help)
We installed Tortoise and created user that way also
the Tortoise cash the user and perhaps use the puskOk software that user?
But it didn't help either...
