3874 usri11_auth_flags specifies the account operator privileges. The
3875 possible values are:

3888 AF_OP_COMM 1 Communications operator
3889 AF_OP_SERVER 2 Server operator
3890 AF_OP_ACCOUNTS 3 Accounts operator
3891
3892
3893 usri11_password_age specifies how many seconds have elapsed since the
3894 password was last changed.
3895
3896 usri11_home_dir points to a null terminated ASCII string that contains
3897 the path name of the user's home directory.
3898
3899 usri11_parms points to a null terminated ASCII string that is set
3900 aside for use by applications.
3901
3902 usri11_last_logon specifies the time when the user last logged on.
3903 This value is stored as the number of seconds elapsed since
3904 00:00:00, January 1, 1970.
3905
3906 usri11_last_logoff specifies the time when the user last logged off.
3907 This value is stored as the number of seconds elapsed since
3908 00:00:00, January 1, 1970. A value of 0 means the last logoff
3909 time is unknown.
3910
3911 usri11_bad_pw_count specifies the number of incorrect passwords
3912 entered since the last successful logon.
3913
3914 usri11_log1_num_logons specifies the number of times this user has
3915 logged on. A value of -1 means the number of logons is unknown.
3916
3917 usri11_logon_server points to a null terminated ASCII string that
3918 contains the name of the server to which logon requests are sent.
3919 A null string indicates logon requests should be sent to the
3920 domain controller.
3921
3922 usri11_country_code specifies the country code for the user's language
3923 of choice.
3924
3925 usri11_workstations points to a null terminated ASCII string that
3926 contains the names of workstations the user may log on from.
3927 There may be up to 8 workstations, with the names separated by
3928 commas. A null strings indicates there are no restrictions.
3929
3930 usri11_max_storage specifies the maximum amount of disk space the user
3931 can occupy. A value of 0xffffffff indicates there are no
3932 restrictions.
3933
3934 usri11_units_per_week specifies the equal number of time units into
3935 which a week is divided. This value must be equal to 168.
3936
3937 usri11_logon_hours points to a 21 byte (168 bits) string that
3938 specifies the time during which the user can log on. Each bit
3939 represents one unique hour in a week. The first bit (bit 0, word
3940 0) is Sunday, 0:00 to 0:59, the second bit (bit 1, word 0) is

3951 Sunday, 1:00 to 1:59 and so on. A null pointer indicates there
3952 are no restrictions.
3953
3954 usri11_code_page specifies the code page for the user's language of
3955 choice
3956
3957 All of the pointers in this data structure need to be treated
3958 specially. The pointer is a 32 bit pointer. The higher 16 bits need
3959 to be ignored. The converter word returned in the parameters section
3960 needs to be subtracted from the lower 16 bits to calculate an offset
3961 into the return buffer where this ASCII string resides.
3962
3963 There is no auxiliary data in the response.
