security = domain and username map necessity

[Lionel MAZE]

Hi,

I have installed a SAMBA server 2.0.10 on COMPAQ Tru64.
I have added my UNIX server in NT domain with Server Manager on my PDC.
I have created a smb.conf file using SWAT and I have added a share.
Then I have started samba as daemon. I can see the unix server in my
browser and I can see the share too but I can't access it unles I use a
username map file.
What's wrong ?

Lionel.
