SAP Issue - 4008 - Login SLD Failed, make sure the company and user credentials are correct

This note is only for SAP 9.2 PL10/PL11. If you get a "4008" error in another version please refer to this article.

[Legacy note] This version is not supported anymore, if you have this issue, please upgrade the B1UP/SAP installation.

*UPDATE 16.4.2018*

This error has been fixed in SAP version 9.3 PL01.

Q: What is the issue?
You can get an error "4008 - Login SLD Failed, make sure the company and user credentials are correct" in SAP Client startup, CRM 4 Outlook configuration, iPayment configuration, or anywhere where a connection to the company database is made. Currently, we've only seen SAP versions 9.2 PL10 and higher affected.

Q: What can you do about it?
As for now we only have an SAP note available here: https://launchpad.support.sap.com/#/notes/2541939, however, the workaround suggested does not work with our add-ons. We use OUSR UDF records in our products and we cannot delete them.

Q: Is there a workaround?
Unfortunately, there is no workaround available right now. The best action is to contact SAP support and make them more aware that the bug is causing problems. Only SAP is able to fix this problem.
