At first my English is not so good, sorry for this.
At secound this Project are wonderful News for me.
But I have the same Problem than two other users
When I will work with Krusader to Admin than he will have the root password.
Thats the Problem, no chance to give him the password. Yes kdesudo-trinity is installed.
The System is Debian Squezze and KDE 3.5.12 is the Standalone Desktop.
What you say to the other with this Problem, I also do this.

I hope you have a way for this Problem.
