3907
3908
3909 usri11_password_age specifies how many seconds have elapsed since the
3910 password was last changed.
3911
3912 usri11_home_dir points to a null terminated ASCII string that contains
3913 the path name of the user's home directory.
3914
3915 usri11_parms points to a null terminated ASCII string that is set
3916 aside for use by applications.
3917
3918 usri11_last_logon specifies the time when the user last logged on.
3919 This value is stored as the number of seconds elapsed since
3920 00:00:00, January 1, 1970.
3921
3922 usri11_last_logoff specifies the time when the user last logged off.
3923 This value is stored as the number of seconds elapsed since
3924 00:00:00, January 1, 1970. A value of 0 means the last logoff
3925 time is unknown.
3926
3927 usri11_bad_pw_count specifies the number of incorrect passwords
3928 entered since the last successful logon.
3929
3930 usri11_log1_num_logons specifies the number of times this user has
3931 logged on. A value of -1 means the number of logons is unknown.
3932
3933 usri11_logon_server points to a null terminated ASCII string that
3934 contains the name of the server to which logon requests are sent.
3935 A null string indicates logon requests should be sent to the
3936 domain controller.
3937
3938 usri11_country_code specifies the country code for the user's language
3939 of choice.
3940
3941 usri11_workstations points to a null terminated ASCII string that
3942 contains the names of workstations the user may log on from.
3943 There may be up to 8 workstations, with the names separated by
3944 commas. A null strings indicates there are no restrictions.
3945
3946 usri11_max_storage specifies the maximum amount of disk space the user
3947 can occupy. A value of 0xffffffff indicates there are no
3948 restrictions.
3949
3950 usri11_units_per_week specifies the equal number of time units into
3951 which a week is divided. This value must be equal to 168.
3952
3953 usri11_logon_hours points to a 21 byte (168 bits) string that
3954 specifies the time during which the user can log on. Each bit
3955 represents one unique hour in a week. The first bit (bit 0, word
3956 0) is Sunday, 0:00 to 0:59, the second bit (bit 1, word 0) is

3971 choice
3972
3973 All of the pointers in this data structure need to be treated
3974 specially. The pointer is a 32 bit pointer. The higher 16 bits need
3975 to be ignored. The converter word returned in the parameters section
3976 needs to be subtracted from the lower 16 bits to calculate an offset
3977 into the return buffer where this ASCII string resides.
3978
3979 There is no auxiliary data in the response.
