Issue with language specific characters combined with AD-Logon to BO platform and client tools

We are using SSO via Win AD to logon to BO-Launchpad. Generally this is working which means for Launch Pad no manual log on is needed. But  this is not working for users which have language specific letters in their AD name (e.g. öäüéèê...).

What we have tried up to now:

  • If the AD-User name is Test-BÖ the log on is working with the user name Test-BO with logon type AD
  • If the logon Type "SAP" is used than it is possible to use the name Test-BÖ as the username
  • Generally it is no problem in AD to use language specific letters (which means it is possible to e.g. log on to Windows with the user Test-BÖ)
  • It is possible to read out the AD attributes from BO side and add them to the user. Which means in the user attributes the AD name Test-BÖ is shown via automatic import from AD. So it's not the problem that the character does not reach BO.
  • I have opened a ticket concerning that. SAP 1th level support is telling me that this is not a BO problem. They say it is a problem of Tomcat. I don't believe that because the log on with authentification type SAP is working.
  • I have set up the same combination (AD User Test-BÖ with SAP User Test-BÖ) as a single sign on authentification in SAP BW and there it is working without problems.

Which leads me to the conlusion: It is not a problem of AD. It is something which is connected to the BO platform but only combined with logon type AD because SAP Logon is working with language specific characters.

I have found this article with BO support:

You cannot add a user name or an object name that only differs by a character with a diacritic mark

Basically this means AD stores the country specific letters as a base letter internally. Which means that if you have created a user with a country specific letter in the name you can also logon with the Base letter to Windows.

SAP-GUI and Windows are maybe replacing the country specific letters by the base letter. Due to that SSO is working. BO seems not to be able to do that. Up to now the supporter from BO is telling me that this is not a BO problem.

Seems to be magic that the colleagues of SAP-GUI are able to to it.
