Be sure your ldap-client with getent group and getent passwd is working for
your ldap server on the member server.
Remove your member server again from your ldap-tree.
Stop samba on your member server. Delete your secrets.tdb in /etc/samba.
My config of my member server:
Preferred master=no
Local master=no
Domain master=no
Wins server=your.domain.server
#to be shure
Ldap admin dn=cn=youradmin,dc=your,dc=domain
Ldap suffix=dc=your,dc=domain
Ldap group suffix= ou=yourgoups
Ldap user suffix=ou=youusers
Ldap machine suffix= ou=yourmachines
Ldap idmap suffix= ou=Idmap
Idmap backend=ldap:ldap://yourldapserver
Idmap uid=10000-20000
Idmap gid=10000-20000

Then smbpasswd -a -e root ; must be the same password as for your samba pdc

/usr/bin/net rpc join -S PDC-host-name -Uadminuid%adminpass

Then service smb start

Working for me on any member server

Good Luck

I have a similar installation, but works fine.
PDC: samba 3.4.5 ( use source) and ldap
member server: samba-3.0.28 (comes with RHEL 5.2)
On member server, I did this:
# /usr/bin/net rpc join -S PDC-host-name -Uadminuid%adminpass
# service smb start

Can you make sure
1. there is no ldap config in smb.conf on the member server;
2. getent passwd / getent group show you the same results on PDC and 
member server.
