    We got this error while testing scp/ssh based password-less authentication

    AUDIT: CHFW0019I: The Transport Channel Service has started chain HttpOutboundChain:servernamexxxx:9080.
    Could not load module /usr/share/centrifydc/lib/
    Dependent module /opt/freeware/lib64/libgcc_s.a(shr.o) could not be loaded.
    The module has an invalid magic number.
    Could not load module scp.
    Dependent module /usr/share/centrifydc/lib/ could not be loaded.
    Could not load module .

    Any idea why ? Is it something to do with directory permissions ?
