Hello Carsten,
The Product Availability Matrix (PAM) is the official source to find supported product versions dependencies.
According to the PAM for SAP SSO 2.0 SP03 the Secure Login Library supports the SAP ABAP Applications Server Versions 4.6C, 6.20, 6.40, 7.0x, 7.1x, 7.2x and 7.3x (on the Operating systems listed on the same page 11 of the PAM document).
Best regards,
Donka Dimitrova
