This is an odd one... I have several FC1 based servers which are making use of nss_ldap and pam_ldap for user logins and user information. Everything works great except mysteriously some cron jobs don't seem to run and none will email their output to root... UNTIL .. I disable LDAP.
I did have the same problem with Fedora 1 and csh/tcsh.
It disapears with Fedora 2 with most of my LDAP Problems.
