JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE

[Former Member]

Hi all,

While create JCO connectivity, I encounter following error.

com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: This system rejects all logons using SSO tickets.

The user authenticaltion method used is ticket, please note that it is successful in case of user/password.

Any clues.

Regards.

Where is the JCO connecting to?

Lets say its a ABAP backend system then you must check atleast:

1. login/accept_sso2_ticket is set..

see: http://help.sap.com/saphelp_nw70/helpdata/EN/99/15ee3adcf1913fe10000000a11405a/frameset.htm

2a. Certificate is uploaded in the store

2b. Certificate is added to ACL

for both 2a and 2b see: http://help.sap.com/saphelp_nw70/helpdata/EN/78/f1a8490e7011d6999500508b6b8a93/frameset.htm

Good Luck,
