Review Comment:
   Hi @ChrisSamo632,
   I tried your suggestion on branch **nathluu/registry-mssql-b** but it does not work.
   Caused by: org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [INSERT INTO UGP_USER(IDENTIFIER, "IDENTITY") VALUES (?, ?)]; nested exception is java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"IDENTITY") VALUES ('76137000-a35a-3bb2-94d7-2f5bac309242', 'CN=user2, OU=nifi')' at line 1
