NIS to ldap layout

[Eric Ritchie <eritchie@interactivebrokers.com>]

I have 3 NIS domains I wish to convert to ldap. I would like to keep 3 
separate areas in ldap since the NIS domains have different accounts. I 
created a base dn and loaded data under 3 higher levels, such as base is 
dc=xyz,dc=com and dc=a,dc=xyz,dc=com  dc=b,dc=xyz,dc=com  
dc=c,dc=xyz,dc=com. Then if I want client one to be in domain a, I set 
its base to dc=a,dc=xyz,dc=com. This works for host name lookups but 
when another host tries to login to the box via telnet or rsh, the login 
hangs after the password is entered, ssh works though. If I specify a 
binddn on the client with dc=a,dc=xyz,dc=com, I can login via telnet and 
rsh but name lookups fail on the host. Any idea what is causing this? Is 
this the best way to have separate DBs for clients?

Thanks
