I actually started trying to solve this in their IRC channel, but
eventually it was suggested that it might be something specific to svn.
After your reply I spoke with some people via Phabricator's web chat
interface and at their suggestion I will be opening a task for this
issue. I'm still not sure if this is a Phabricator issue or a
Subversion one, or some combination of the two, but hopefully between
this mailing list and the developers from the Phabricator team, a
solution will be found soon.

Speaking of the mailing list, I noticed on http://svn.haxx.se/users/
that there were recently some replies in this thread that I seem not
to have received. I'm not sure if there is a better way for me to reply
to these or not, so I will do so here.

  Guten Tag foven,
  am Donnerstag, 3. Dezember 2015 um 21:55 schrieben Sie:

  Did you have a look at that script, is it maybe doing more than just
  authorization? Does it handle svn+ssh different from if you ssh and
  execute svn commits using file:///?

  Mit freundlichen Grüßen,
  Thorsten Schöning

    I will look into this, but I'm fairly sure that authorization is all
    it does. The documentation for sshd_config states that this
    property "specifies a program to be used to look up the user's
    public keys". It "should produce on standard output zero or more
    lines of authorized_keys output".

    So far as a difference between svn+ssh and ssh followed by svn
    commits using file:///, I'm pretty sure the way that instance of
    sshd is configured, it isn't possible to simply ssh in and then run
    commands. I'm not able to access the server at the moment, but I
    don't think it is possible. There is another sshd instance
    running however, with a more typical configuration and that is the
    one where I was able to ssh, then svn commit file:///.

  Is SELinux enabled?

    No, SELinux is disabled.
