Thanx, but it does not help tough. The error remains the same.

An strace shows me that afsperf is trying to read some kerberosIV/V stuff
like "/etc/krb.extra" and "/etc/krb.realms"... Hmmm, is it really true, that
afsperf works with openafs without arla and real kerberos installation on
the client and / or server? Fyi: we are using kaserver.

Thank you in advance.
