Hi. Good idea -- I have added support for this now, see:
https://gitlab.com/gsasl/gsasl/-/merge_requests/5/commits
https://gitlab.com/gsasl/gsasl/-/merge_requests/5/diffs
Please try building from git or test a tarball:
https://gitlab.com/gsasl/gsasl/-/jobs/2794287493/artifacts/file/gsasl-2.0.1.8-90f5.tar.gz
Consider it untested! It would be nice to interop test this against
some other implementation, is anyone aware of any?
