samba - Nov 2003 - Client accessing Samba doesn't authenticate against A ctive Directory

| When a Windows client attempts to browse shares on a Samba 3.0 server
| authenticating against a Windows 2003 Active Directory domain, it
| requests credentials. Typing in user name and password fails

I am having this exact same issue.  Attached is a sample copy of my smb.conf
and krb5.conf along with some errors I got from the smbd logs (max debug
level).

smb.conf
----
[global]
        server string = Samba 3.0.0
        workgroup = DOMAIN
        hosts allow = 192.168.3. 127.
        security = ADS
        realm = DOMAIN.COM
        client use spnego = yes
        password server = ads.domain.com
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
        local master = no
        domain master = no
        preferred master = no
        domain logons = no
        name resolve order = host
        dns proxy = yes
 

[test]
        comment = Test Share
        path = /home/user/test
        read only = no
        browsable = yes
        writable = yes
        guest ok = yes

krb5.conf
----
[logging]
 default = FILE:/var/log/krb5libs.log

[kdc]

 }

Anyone run into this as well?

Looks like you don't have the MIT krb5 1.3.1 libs or the
latest version of Heimdal (don't remembe which version
you need...cvs development snapshot maybe).
