[tdh@camp5 privilege]$ svn checkout svn+ssh://email@example.com/cvs/projects/privilege/trunk sh: -c: line 0: syntax error near unexpected token `(' sh: -c: line 0: `svnserve --tunnel-user (null) -t' svn: Connection closed unexpectedly
Our restricted login shell is trying to add "--tunnel-user username" on
the svnserver command line, and is unable to get your username.

to your $HOME/.ssh/config file and make sure you use the "-f" flag to kinit (so your ticket is forwardable) and
all should be well.
Note that for newer ssh's, you may also need to add
in the $HOME/.ssh/config as well; older versions won't accept that option.
