Description	Error changing password. Password does not conform to password policy for user. %ruser = %1 %rhost = %2
Event Information	According to Microsoft : Cause : This event is logged when error changing password. Resolution : Check password policy An error occurred while changing the password because the password does not conform to password policies that apply to the user. In the Windows environment, security policy settings control password policy. The section of security policy that includes password policies is typically called Account Policy. To check password policy for the domain: On the domain controller on which Password Synchronization is running, click Start , click Administrative Tools , and then click Local Security Policy . In the hierarchy pane of the Local Security Policy MMC, expand Account Policies . Select Password Policy . In the results pane, double-click any of the listed password policies, or right-click a policy and then click Properties , to view its properties. Verify : To verify the functional state of UNIX to Windows password synchronization, retry UNIX to Windows password synchronization. UNIX to Windows password synchronization is fully operational when the password synchronization succeeds, and functioning with warning conditions present if password synchronization fails for some passwords but succeeds for others. If password synchronization succeeds for some passwords but fails for others, the UNIX to Windows Password Synchronization Service is likely fully operational, but there might be account- or computer-specific configuration problems preventing password changes from being synchronized on UNIX-based hosts.
