Sounds like an ifdef GLIBC20 is needed and a configure test for glibc2.0 vs
glibc2.1 might be needed here.

Hmm, first one is to access the logon script.  The second one may be to
access profiles or policies. Where does your logon home or logon path point
to? Is the client trying to access profiles?

To track it down may require a trace, which can be obtained with tcpdump.
