samba - Jan 2004 - Roaming Profiles Refuse to Load on MS Windows Clients

I am unable to get roaming profiles to work correctly when using a Samba 
3.0.1 server with Windows 2000 and XP Pro clients. The MS Windows 
clients will only load the default profile but will stubbornly refuse to 
load their profile from the Samba server, even though when the user logs 
off, their profile is correctly written to /home/samba/profiles/username.

I have even tried the following ?Group Policy? options under the MMC:

?Do not check for user ownership on Roaming Profile Folders?
?Delete cached copies of roaming profiles?
?Do not detect slow network connections?
?Wait for remote user profile?
?Add the Administrators security group to roaming user profiles?

None of these group policy options remedied this problem.

I have set permissions on /home/samba/profiles to 1757.

I have tested smbldap-tools-0.8.2 and commented out line 200 of 
smbldap_conf.pm so it would use the smb.conf 'logon path' directive. I 
have also tested
smbldap-tools-0.8.3 and edited line 143 of 
/etc/smbldap-tools/smbldap.conf to set 
userProfile="\\pdc-srv\profiles\". I still get the same results with 
both of these tests.

Here is my smb.conf that I am currently using:

[global]
workgroup = biologicaqua
server string = Samba Server

Any help and advice would be greatly appreciated.
