[cvsnt] "Can only specify directories for this command"

[Shepherd]

When I tried to set branch access permission by
    "cvs chacl -r sal-dev li:rwc sal"
it showed to me this message:
    "cvs [chacl aborted]: Can only specify directories for this command".
I used this command in my working diretory where the module "sal" is checked
out.

Another problem: I couldn't check out a branch by command.
    D:\eclipse\workspace>cvs checkout -r sal-dev sal
    cvs [server aborted]: no such tag sal-dev
I tagged in eclipse. I found that in the file "Entries" there was a string
"/TSAL-Dev",did it mean the tag was "SAL-Dev"?

Thank all for your help.
