The function is_lasso_ecp_enabled() in saml2idp.py was testing for a specific lasso version. That has proved problematic because we've had too many "unofficial" versions floating around and sometimes the version check produces the wrong result.

A better test, as was discussed in the team meeting is to test for the presence of a symbol in the lasso library we know will only be there with full ECP support.

This issue ticket was originally removed from the tracker as it clashed with the pull request.
