Ah, PAM again, like every 6 months or so. So here's the history:
- First there was the PAM extension from PECL which was abandoned quickly
- A fork was created that made it into Debian
- The PECL version was picked up again, maintained and kept up to date.
- The two versions diverged and we had a switch in our PAM driver to  
support both.
- At one point we decided to drop support for the Debian version  
because it was only available there and no longer actively developed,  
unlike the PECL version.
- Through all this time, the PECL version required pass-by-reference to work.
- Today, the PECL version seems abandoned again, the Debian version is  
still only available there (state unknown), has even been remove from  
Ubuntu.
- Yet it's still the only way to authenticate with system users, and  
we use it for Horde internally too.

We could simply skip the error parameter to work around this. We would  
lose detailed error messages, but at least we won't have to drop the  
driver completely.
