[syslog-ng]Syntax error in default config?

Hello, i'm new to syslog-ng and recently compiled and installed it (version 1.9.4) on my system (LFS, Kernel 2.6.11.7). The problem i have is that even with the default configuiration file it claims to have syntax errors. The lines causing the errors are: destination user { file("/var/log/user.log"); }; and filter f_auth { facility(auth); }; Whereas the first problem is generated due to the fact the the identifier is called "user". If i call it "user_" it works fine. With the second line the problem is "auth" because facility(authpriv) is accepted. But why not auth?! I'm really at a loss with that. I hope someone here has an idea what might be the problem. Thanks in advance. Regards, J. Meub
