 ### Konfiguration
 
 Zur Konfiguration der Credentials der Buckets dient das Property ***mobidam.s3.bucket-credential-config***.
-Dieses ist als Map gestaltet und enthält für jeden benannten Bucket die Namen von Umgebungsvariablen für Access-Key und Secret-Key:
+Dieses ist als Map gestaltet und enthält die default Tenant-Credentials. Nach Bedarf können der Access-Key und Secret-Key für die einzelnen Buckets separat konfiguriert werden:
 ```
-x-itmkm82k:
-  access-key-env-var: MOBIDAM_BUCKET1_ACCESS_KEY
-  secret-key-env-var: MOBIDAM_BUCKET1_SECRET_KEY
+tenant-default:

 int-mdasc-mdasdev:
   access-key-env-var: MOBIDAM_BUCKET2_ACCESS_KEY

 ```
 Die Umgebungsvariablen müssen entsprechend in der Laufzeitumgebung bereitgestellt werden:
 ```
