+ID:          issue-7611
+ISSUE:       https://github.com/FirebirdSQL/firebird/issues/7611
+TITLE:       Can't backup/restore database from v3 to v4 with SEC$USER_NAME field longer than 10 characters.
+DESCRIPTION: 
+    Test uses .fbk which was created in FB 3.x as it is described in the ticket.
+    We restore from this DB using LOCAL protocol and check that it completes OK.
+NOTES:
+    [04.06.2023] pzotov
+    ::: NB ::: Problem can be reproduced only if we restore via LOCAL protocol rather than remote.
+    Confirmed bug on 4.0.3.2949, 5.0.0.1066.
+    Checked on 4.0.3.2950, 5.0.0.1067 - all fine.
