I can change ldap account's password by FDS console. The change will sync to my AD soon, then I can logon windows system successfully with new password.

And if I finish the same work by using "passwd" command in linux. The change will still happen in ldap server (so I can logon linux system)and sync to AD.successfully, but I'll fail to logon windows system with any password, whatever new or old one. What's the possible cause for this? Please help, thanks a lot.
