SAP GUI 8 64 bit and SNC error: GSS-API: An invalid name was supplied, Import of a name failed

[DieterLorenz]

Hello community,

I am getting this error Message:

Sapgui 800 [Build 9058] Mon Nov 13 10:50:05 2023
: 'GSS-API(maj): An invalid name was supplied
Import of a name failed
name="p:XXXXXX"

Time Mon Nov 13 10:49:52 2023
Component SNC (Secure Network Communication)
Release 753
Version 6
Module D:/depot/bas/753_REL/src/krn/snc/sncxxall.c
Line 2738
Method SncPGSSImportName
Return Code -4
System Call gss_import_name

Counter 7

I update the newest SAP Kernel 753_1200 and download the newest Note 2115486 GSSKRB5.DLL & GSSNTLM.DLL

Install a fresh Windows Server 2022 and install only the SAP GUI 64 bit Edition.

The SNC Lib was set by the setup correctly and dll are existing:

SNC_LIB=C:\Program Files (x86)\SAP\SNCEncryption\x86\sapsncencryption.dll

SNC_LIB_64=C:\Program Files (x86)\SAP\SNCEncryption\x64\sapsncencryption.dll

The sap user is different than the windows user but the canonical name is the same as the windows login.

The 32 bit SAP GUI Version works fine, but the developer need the SAP Gui 64 bit !

The customer is using only the SNC authentication.

Any ideas ?

Thanks a lot !

This error will be shown when the SNC name you have configured in SAP GUI is not the correct syntax or format for the SNC library you are using. You have masked this value in your image so it is not easy to tell you what is wrong with it.
