Hi,

Here is the information on the installed versions:

Samba:

ldapsmb-1.31-0.46
libsmbclient-3.0.14a-0.4
libsmbclient-devel-3.0.14a-0.4
samba-3.0.14a-0.4
samba-client-3.0.14a-0.4
samba-pdb-3.0.14a-0.4
samba-vscan-0.3.6-0.5
samba-winbind-3.0.14a-0.4

Kerberos:

heimdal-0.6.1rc3-55.3
pam_krb5-1.3-201.1

I am using samba to autheticate against the Windows 2003 AD domain. I can very well 
connect to the domain, get the kerberos ticket. I can also browse the username
and groups on 

the AD. The problem is show in the winbind logs. When intially start the winbind
and smb 

daemon i can connect to the samba shares with the AD username and password from
windows xp. But after sometime it does not authenticate at all nor the AD users
nor the local ones. Here is the log show by the winbind:

I am really frustrated out of this one. 

Thanks in advance.
