I am new to otrs. I have just installed otrs 3.3.5 and it is working. I am getting the following errors when integrating it to opennms.

TicketCreate: UserLogin, CustomerUserLogin or SessionID is required!

Is it possible to add an Agent user on otrs.properties in the opennms? 
If it is not possible, I have created an Agent User with the same credentials as the SOAP User called opennms. 
How can I make otrs use the SOAP user credentials for UserLogin? 

Kind regards
