Hiya I Have configured my samba machine as a member of Windows AD (win2k3 Machine). All the configuration went on successfully when I execute net ads testjoin ; I get output as "OK" and I can see my samba machine in AD computers and users. also i get a proper output from wbinfo -u -g. My kerberos tickets are valid. Now the problem I'm facing is Case1: When I enter the machine name of my samba server in Run Box Of Winxp it is popping up for a user name and pass like Samba/<username> (where Samba = my samba server name) when I enter a valid ADS domain user name it doesnt validate it but when I enter a valid linux user/pass it gets authenticated. Now in Case 2: when I'm entering the ip address of my samba server in "Run" Box it is asking for TIPTON1/<username (where TIPTON1=my ads name) when I enter a valid user and pass of windows it doesnt authenticate also when I enter a valid user and pass of linux it doesnt authenticate. The Only Condition when I'm able to access the samba shares is when I log into winxp with my ADS Domain Profile and try to access the Samba share from My Network Places><ADS DOMAIN>Samba Domain. I would like to use all the ADS accounts to authenticate the users and i dont want to use my linux users n passes. Here is my winbind log >> http://pastebin.ca/726764 my smb.conf >> http://pastebin.ca/726761 my smbd.log >> http://pastebin.ca/726762 Please help me out. Thanks
