4119
4120 usri11_password_age specifies how many seconds have elapsed since the
4121 password was last changed.
4122
4123 usri11_home_dir points to a null terminated ASCII string that contains
4124 the path name of the user's home directory.
4125
4126 usri11_parms points to a null terminated ASCII string that is set
4127 aside for use by applications.
4128
4129 usri11_last_logon specifies the time when the user last logged on.
4130 This value is stored as the number of seconds elapsed since
4131 00:00:00, January 1, 1970.
4132
4133 usri11_last_logoff specifies the time when the user last logged off.
4134 This value is stored as the number of seconds elapsed since
4135 00:00:00, January 1, 1970. A value of 0 means the last logoff
4136 time is unknown.
4137
4138 usri11_bad_pw_count specifies the number of incorrect passwords
4139 entered since the last successful logon.
4140
4141 usri11_log1_num_logons specifies the number of times this user has
4142 logged on. A value of -1 means the number of logons is unknown.
4143
4144 usri11_logon_server points to a null terminated ASCII string that
4145 contains the name of the server to which logon requests are sent.
4146 A null string indicates logon requests should be sent to the
4147 domain controller.
4148
4149 usri11_country_code specifies the country code for the user's language
4150 of choice.

4152 usri11_workstations points to a null terminated ASCII string that
4153 contains the names of workstations the user may log on from.
4154 There may be up to 8 workstations, with the names separated by
4155 commas. A null strings indicates there are no restrictions.
4156
4157 usri11_max_storage specifies the maximum amount of disk space the user
4158 can occupy. A value of 0xffffffff indicates there are no
4159 restrictions.
4160
4161 usri11_units_per_week specifies the equal number of time units into
4162 which a week is divided. This value must be equal to 168.
4163
4164 usri11_logon_hours points to a 21 byte (168 bits) string that
4165 specifies the time during which the user can log on. Each bit
4166 represents one unique hour in a week. The first bit (bit 0, word
4167 0) is Sunday, 0:00 to 0:59, the second bit (bit 1, word 0) is

4182 choice
4183
4184 All of the pointers in this data structure need to be treated
4185 specially. The pointer is a 32 bit pointer. The higher 16 bits need
4186 to be ignored. The converter word returned in the parameters section
4187 needs to be subtracted from the lower 16 bits to calculate an offset
4188 into the return buffer where this ASCII string resides.
