ISSUE:       6346
TITLE:       Connection does not see itself in the MON$ATTACHMENTS when Domain/Username (using SSPI) is 31 bytes long
DESCRIPTION:
  Could not reproduce bug on WI-V3.0.4.33054, discussed this with dimitr and alex.
  Problem can appear randomly when some byte in memory contains value not equal to 0x0.
  NB:
  1. ISC_* variables must be removed from environtment for this test properly run.
  2. Length of non-ascii user must be equal to maximal possible for tested FB: 31 for 3.x and 63 for 4.x+
JIRA:        CORE-6097
FBTEST:      bugs.core_6097
NOTES:
     [17.06.2022] pzotov
     Checked on 4.0.1.2692, 3.0.8.33535.
