SM59 - Name or password is incorrect (repeat logon)
I am facing a weird situation.
I created a RFC type 3 and when I perform the Test Authorization , I get the error message:
Name or password is incorrect (repeat logon)
I can logon target system with the same user and password which I set in the RFC.
Are you creating RFC between NW7.0 and NW6.40 systems? If yes, then this issue will happen because of the earlier short passwords and now long password capability of sap.
There are methods to rectify this... but as a workaround, do one thing, keep your password within 8 characters and all letters should be in caps.. do it and the RFC will work fine.
