3356 This value is stored as the number of seconds elapsed since
3357 00:00:00, January 1, 1970. A value of 0 means the last logoff
3358 time is unknown.
3359
3360 usri11_bad_pw_count specifies the number of incorrect passwords
3361 entered since the last successful logon.
3362
3363 usri11_log1_num_logons specifies the number of times this user has
3364 logged on. A value of -1 means the number of logons is unknown.
3365
3366 usri11_logon_server points to a null terminated ASCII string that
3367 contains the name of the server to which logon requests are sent.
3368 A null string indicates logon requests should be sent to the
3369 domain controller.
3370
3371 usri11_country_code specifies the country code for the user's language
3372 of choice.
3373
3374 usri11_workstations points to a null terminated ASCII string that
3375 contains the names of workstations the user may log on from.
3376 There may be up to 8 workstations, with the names separated by
3377 commas. A null strings indicates there are no restrictions.
3378
3379 usri11_max_storage specifies the maximum amount of disk space the user
3380 can occupy. A value of 0xffffffff indicates there are no
3381 restrictions.
3382
3383 usri11_units_per_week specifies the equal number of time units into
3384 which a week is divided. This value must be equal to 168.
3385
3386 usri11_logon_hours points to a 21 byte (168 bits) string that
3387 specifies the time during which the user can log on. Each bit
3388 represents one unique hour in a week. The first bit (bit 0, word
3389 0) is Sunday, 0:00 to 0:59, the second bit (bit 1, word 0) is
3390

3400 Sunday, 1:00 to 1:59 and so on. A null pointer indicates there
3401 are no restrictions.
3402
3403 usri11_code_page specifies the code page for the user's language of
3404 choice
3405
3406 All of the pointers in this data structure need to be treated
3407 specially. The pointer is a 32 bit pointer. The higher 16 bits need
3408 to be ignored. The converter word returned in the parameters section
3409 needs to be subtracted from the lower 16 bits to calculate an offset
3410 into the return buffer where this ASCII string resides.
3411
3412 There is no auxiliary data in the response.
