No login to Backend possible after installation

Hello,
I tried to install the version typo3 11.5.1 in an OpenSuse Leap 15.3 linux environment.
The installation steps could be performed without any error but at the end there is no login to the backend possible: There is no login directory in the installation path as requested by the URL …
Has anybody an idea how to solve this issue?
Many thanks for the support
Best Regards
Migo
