Using Subversion with Apache, PAM and RADIUS

[Herb Schilling <hs...@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.
