[Koha] z3950-daemon-launch.sh - Account not available in Linux

Hi everyone, I've been testing Koha in Redhat 4 Enterprise ES (update 2). Installation going well. But I have a little problem when executing z3950-daemon-launch.sh it's appear a message: This account is currently not available. I'm not very familiar with latest Redhat environment. Can anybody help me out? Thanks in advance. Amzari Abu Bakar __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
