I'd guess this is a pam issue, not a Horde issue. It is common for pam+su
to fail if there is no terminal associated with the process doing su.
I can reproduce this on most systems by using pam+su, setting a restriction
in /etc/security/access.conf (or similar file), and trying to do an su
with stdin redirected to /dev/null.

Best bet, use some other authentication method. Next best bet, debug why
su is failing, and work around it...
