[Samba] DOS clients problem with 3.6.22 vs 3.6.18

[Dominic Raferd]

I have tried to upgrade our samba server from 3.6.18 to 3.6.22 but found 
that our DOS clients could no longer connect (using DOS 6.22 and 
Microsoft LAN Manager 2.1).

With 3.6.18 we use smb.conf setting 'min protocol = LANMAN2' and it 
works great, with 3.6.22 although clients can connect ok, they cannot 
obtain a directory listing. Instead the first file (sometimes misnamed) 
just relists endlessly.

Using loglevel 4 I find this text in log file when a DOS client connects 
to either version of samba 3.6:

   Requested protocol [PC NETWORK PROGRAM 1.0]
   Requested protocol [MICROSOFT NETWORKS 3.0]
   Requested protocol [DOS LM1.2X002]
   Selected protocol DOS LM1.2X002

It seems like there is a bug in 3.6.22 or is there a new setting that 
might work with 3.6.22 to get it working again? (Sorry I am unable to 
try 3.6.23 but I see nothing in the changelog which suggests that this 
problem might go away with 3.6.23.)

Thanks for any help
