Using Subversion with Apache, PAM and RADIUS

From: Herb Schilling <hschilling_at_nasa.gov>

Hi,

  I am trying to get Subversion to authenticate against a RADIUS
server via PAM. Everything is running on a Fedora Core 3 system using
the latest Apache PAM module and the latest RADIUS module for PAM.

  Everything works fine when I access the repository using a browser.
I get prompted for a user name and passcode and I can see the files
in the repository.

  The problem occurs when using the svn command line tool. By adding
some debugging statements to the modules I can see that when doing
a"svn list" there are 3 authentication attempts all using the same
passcode that I entered just once. The first authentication succeeds
but the next two don't because you can't use a passcode more than
once. So the whole "svn list" command fails.

  When I look at the repository from a browser only one authentication
happens and that succeeds so the whole "command" succeeds.

  It almost seems like this can't work but I have read that others
have used RADIUS authentication for Subversion. I have spent a lot of
time on this and now I am stuck. What am I missing? I do have
"store-auth-creds" set to yes in my config file. I thought that might
help.

  Thanks in advance.

In theory, there is no difference between theory and practice,  but 
in practice, there is.
