Samba error: session setup failed: Call returned zero bytes (EOF)

[Stuart Bailey]

Hello,
I'm having terrible trouble with Samba.

I've installed from SuSE 9.3 which gives me Samba 3.0.12 - This was later 
upgraded to 3.0.13 by an automatic online update.
I have since upgraded further to 3.0.20 in an attempt to resolve this problem.
So far all these versions behave the same.

I was trying to get Samba to authenticate with openLDAP. The LDAP is running 
fine, and I am using it to authenticate my mail via Cyrus.

My Samba host is helios.

If I execute smbclient -L helios I get the following:
	# smbclient -L helios
	Password:
	Domain=[PERRINGS] OS=[Unix] Server=[Samba 3.0.20-4-SUSE]

        	Sharename       Type      Comment
        	---------       ----      -------
        	profiles        Disk      Network Profiles Service
        	users           Disk      All users
        	groups          Disk      All groups
        	pdf             Printer   PDF creator
        	print$          Disk      Printer Drivers
        	shared          Disk      Shared Folder
        	IPC$            IPC       IPC Service (LinuSoft Samba (3.0.20-4-SUSE) 	
Server)
	        ADMIN$          IPC       IPC Service (LinuSoft Samba (3.0.20-4-SUSE) 
Server)
	Domain=[PERRINGS] OS=[Unix] Server=[Samba 3.0.20-4-SUSE]

	        Server               Comment
	        ---------            -------
	        HELIOS               LinuSoft Samba (3.0.20-4-SUSE) Server

	        Workgroup            Master
	        ---------            -------
	        PERRINGS             HELIOS

Note, I have not yet added any users to the smbpasswd file.

If I now add a user:

	# smbpasswd -a stuart
	New SMB password:
	Retype new SMB password:
	account_policy_get: tdb_fetch_uint32 failed for field 4 (maximum password 	
age), returning 0
	account_policy_get: tdb_fetch_uint32 failed for field 5 (minimum password 
age), returning 0
	Added user stuart.  

Now when I execute smbclient -L helios I get the following:

	# smbclient -L helios
	Password:
	session setup failed: Call returned zero bytes (EOF)

If I now comment out the new user in the smbpasswd file, the service behaves 
as before.


I'm struggling with this now, any comment or help would be gratefully 
received.

Many thanks,

Stuart.
