AS2 Integration – Options for Basic Authentication when receiver restricts username characters

[#1]

Hi SAP Community,

We are implementing an AS2 integration using SAP Integration Suite and need to use HTTP Basic Authentication for the communication. The Basic Auth username generated/provided for our Integration Suite setup contains special characters, specifically characters such as ! and |

My username have this pattern

sb-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx!|rt-integration-suite-dev!xxxxxx

The receiving system, however, validates Basic Auth usernames against a restricted character set:

^[a-zA-Z0-9-_.]+$

Therefore, characters such as ! and | are rejected and the generated username cannot be configured on the receiving side.

The restriction is on the receiving system and not in SAP Integration Suite. 

I would like to understand whether

• SAP Integration Suite provides an alternative username/credential that does not contain these special characters.
• The generated username can be changed or an alias can be used without affecting authentication.

Any experience with this scenario or pointers to relevant SAP documentation would be appreciated.

Thanks,
Abhilash Chandran
