DescriptionError when trying to log into SAP:
This SAP environment is supposed to have single sign on enabled, as well as a secure network connection. We do not think the SNC connection was ever checked. We verified that the SNC option was removed from the environment variables in the SAP GUI Login, as well as modified the saplogon.ini file and removed all traces of single sign on and SNC. We still get the same error.
Applies toThis error generally applies to users who are using SNC and Single Sign On.
CauseThis issue is normally caused when the Single Sign On library which is being used by SAP is not set up to be referenced by our software.
SolutionThis issue can generally be resolved by adding an Environment or System Variable to the user's machine referencing the single sign on library (.dll). This file is normally named gssapi32.dll, gssntlm.dll and can generally be found in the following location: C:\Windows\System32.
To add an Environment or System Variable, complete the following steps:
Open your Start menu and type Environment
- Click either option which mentions Environment Variables (the same window will open)
If your single sign on library (.dll) is located in the default folder (C:\Windows\System32), you should be able to simply add an Environment Variable entry by clicking "New..."
- Variable name: SNC_LIB
- Variable value: single sign on library (e.g. "gssapi32.dll")
- If your single sign on library may be at a different location (non-default), use a System variable (requires Administrator permissions) to specify the specific location in the value (e.g. C:\Windows\...)
