ipa-kdb: provide correct logon time in MS-PAC from authentication time
    
    When MS-PAC structure is created, we get passed the time of
    authentication from KDC. Use this to record logon time in MS-PAC
    structure.
    
    Set allow password change time to the last password change. We need to
    refer to the actual password policy here in future.
    
    Also use INT64_MAX to represent the resulting value for logoff
    and kickoff times according to MS-PAC 2.6.
