RFC Connection Error (Name or password is incorrect)

Updated May 18, 2018

Hello,

I'm not a security expert so I need some help. I had security setup a RFC user and provided the documentation from Synactive. Security said they have the account setup and tested the RFC function successfully. When I try to call an RFC or a Q[Role=xxxx] I get an error that seems to imply a username or password error. I have retyped the password in the profile and can logon to SAP with the user/pass. Is there something in the RFC account I should check?

here is the error -

Name or password is incorrect (repeat logon)

RFC_ERROR_SYSTEM_ FAILURE

RFC connection parameters:
CLIENT=600 USER=GUIXT CODEPAGE=1160 PASSWD=***** **** LANG=E
ASHOST="sdsapecc1. company.com" SYSNR=0 LCHECK=0 USE_SAPGUI=0

Often this error indicates that the password has not been entered in SAP-OSS and SAP-OSS-LIST-O01, or it may have been entered incorrectly.
Most often, the password for the S-User ID in SAP-OSS and SAP-OSS-LIST-O01 has been recently changed, but it has not been updated in the RFC connections.
To Solve this
Enter the RFC connections SAP-OSS and SAP-OSS-LIST-O01.
Click on the pencil icon to enter the 'Edit' mode.
Enter the correct password, and then 'Save' the changes.

Did you encrypt the password in the profile?

Please note: In order to obtain the RFC password in encrypted form
call up GuiXT thus:
guixt RfcPassword

Hi,

please check the uppercase/lowercase issue as described in Q&A Nr. 205 in synactive.com (see below).

Regards,

Q: Our RFC user does not work; we always get the the error message "Invalid user or password". But we are sure that both are correct. What could be the reason?

A: This is probably an issue concerning uppercase/lowercase characters. GuiXT translates the given password to uppercase (unless you enclose it within "....").
This was appropriate for earlier SAP systems but later ones use case sensitive passwords.

I suggest you either use a password that consists of uppercase letters and digits only, or you put it into "...." in the profile. In the case of encrypted password (RfcpasswordEnc) : create the encryption including the "...." and then put the result into the profile without enclosing the encrypted string within "...".

Please note: In order to encrypt a password "xxx" including the "..." characters, you need the MS DOS command

guixt rfcpassword "xxx"

Without the backslash characters the "..." are not included into the encrypted password, since the MS DOS command interpreter treats "xxx" the same way as xxx.

I've tried it both ways: Normal text and Encrypted
