"Cannot write more bytes to the buffer than the configured maximum buffer size: 10485760"

[CTBT]

I´m currently testing to establish a connection to the public DFN-AAI authentication service over saml protocol. We are using the rsk saml2p plugin.

I configured the provider in my local identity server and startet an authentication request. This error occured in the browser after the authentication request: Cannot write more bytes to the buffer than the configured maximum buffer size: 10485760. (details see below)

DFN-AAI provide the metadata-document for there testing-environment under this url: https://www.aai.dfn.de/fileadmin/metadata/dfn-aai-test-metadata.xml The metadata is indeed veeeery large but it´s the official document from the dfn-aai service.

Should i report this issue to RSK, is it an identity server problem or even aspnetcore lib internal ?
