The latest security update to Mac OS 10.5.6, which came out in the last few days, is causing self service iprint printer installs to fail with a syntax error. I'm running NetWare 6.5 sp7. This is very similar to a problem that occurred with a CUPS update to Mac OS 10.5 in March '08. My iprint server seems to be stable, but the clients can't install printers through the self service web page.
