Unable to retrieve Roles - RFC_ERROR_LOGON_FAILURE


Hi everyone,

I've installed BOBJ EDGE STANDARD XI R2, I've deployed the JCo 2.1.8 and the SAP tab under authentication is available.

After adding a system with correct logins, I receive the following error when trying to retrieve roles -

An error occurred while communicating with the CMS.
The following error message was returned:
Name or password is incorrect (repeat logon) 

I've tripple checked the username / password and they are valid when using SapGui.

Only thing that strikes me odd are the two DLLs in the JCO package -

librfc32.dll - 6405.5.165.5297

sapjcorfc.dll - 6400.165.13.29581

I have SAPGui installed on the machine and the librfc32.dll that came with it is of a more advanced version - 7100.3.125.5937 (librfc32.dll), when I overwrote the DLL with the one that came with the JCO package, everytime I tried to log in to the sap system using the SapGui i've received a Message_Type_X error.

Should I use the older DLL that came with the JCO package despite it seems to cause Message_type_x ? (perhaps not rebooting the machine caused the message_type_x?)

Do you have any advice on my main issues - unable to retrieve roles?

I thank you for you time,
