you've put encrypt passwords=yes in your samba config...assuming you didn't
ALSO follow the instructions to switch the windows box to clear-text, the
passwords will be sent encrypted, not clear text.

Greetings,

I have added the nis user name using smbpasswd in my RS6K box, I can see it
in /var/samba/private
I have created the smb.conf file using swat (/http://localhost:901/)
here is my smb.conf file:
ibm210 # cat smb.conf
# Samba config file created using SWAT
# from gritpc27 (128.209.47.196)
# Date: 2003/01/28 11:37:13

# Global parameters
[global]
        workgroup = IFAS
        netbios name = IBM210
        interfaces = en0
        encrypt passwords = Yes
        wins server = 128.209.47.10
        guest account = guest
        hosts allow = 128.209.47. 128.209.60. 127. 128.

[bsarma]
        comment = bsarma's home Directory
        path = /users/bsarma
        username = &+bsarma
        guest account =
        valid users = &+bsarma,root
        admin users = &+bsarma,root
        writeable = Yes

Please let me know if the above settings is ok.

You told me to use the default windes password encryption method, is it
same as passing the clear text. If I choose this method will my win2k pc
pass all the passwords for intranet and internet in clear text?

Please advice.

Regards & Thanks
BN
