ORA-28040: No matching authentication protocol exception is received


Article ID: 7728

CA Test Data Manager (Data Finder / Grid Tools)


While registering a new table in the TDM Portal, I am receiving the following error message: ORA-28040 No matching authentication protocol exception is received. 


This issue is caused by the TDMModelService having two JDBC drivers in the Portal's lib folder. 


CA Test Data Manager (TDM)- Portal


You can resolve this by removing the ojdbc6- file from C:\Program Files\CA\CA Test Data Manager Portal\tomcat\webapps\TDMModelService\WEB-INF\lib\ folder. Once you remove the file, restart the TDM Portal service and the error message should not be seen again.
