Unable to auth

[Gerke Kok]

Hello,
I have a problem to get Cyrus running on RedHat 7.3. I used the rpm's provided by Simon Matter. They install nicely. But I keep getting errors on the authentication ( via saslauthd) Could anyone give any pointers to a solution, please?
This is what syslog sais:
imapd[28564]: cannot connect to saslauthd server: No such file
or directory
imapd[28564]: badlogin: localhost.localdomain[127.0.0.1]
plaintext gerkek SASL(-1): generic failure: checkpass failed

wkr,
Gerke
