I can't log in except with user root

[Andrew]

I'm new to fedora but not new to linux and this one has me confused.  
When I either try to log into FC5 via the gui or ssh I get an error that 
says "Access denied for this host".  I have a ldap running on another 
linux box and thats where I'm pulling this user from.  I'm pretty sure 
that I have ldap setup correctly because when I run getent passwd, 
getent group, getent hosts, and getent shadow I see all of the users, 
groups, hosts that are in ldap.  I don't have any user restrictions on 
ssh and I allowed users to log into the gui.  So what have I missed?

Thanks for your time
