Group Map in SAML provider config can't be saved, not even with the default {} value.

[fwit]

Steps: create/edit SAML provider, leave Group Map at its default {}, click OK.

Error:

The only way to click OK successfully is to clear the field completely (empty). But after saving and reopening the provider, the field shows {} again on its own.

Known issue?

Does no one have the same problem? Is the bug known?

@fwit I can replicate this bug. We'll get it fixed
