# title:        ISQL command SHOW USERS display only me
# decription:
#                  29.07.2016: instead of issuing SHOW USERS which has unstable output (can be changed multiple times!)
#                  it was decided to replace it with SQL query which actually is done by this command.
#                  This query can be easily found in trace when we run SHOW USERS.
#                  Also, we limit output with only those users who is enumerated here thus one may do not warry about
#                  another user logins which could left in securitiN.fdb after some test failed.
#
#                  29.03.2018: changed user names, replaced count of SYSDBA attachments with literal 1.
