Upgraded rhel apache from 2.2 to 2.4 - authz_core:error - AuthType configured with no corresponding authorization directives - 500 error

Question

I upgraded rhel 6 to 7 and it did also the upgrade from apache 2.2 to 2.4 I also have the edgewall trac 1.0.7 version (had to manually deinstall el6 trac10 package and reinstall el7 package). I am using mellond module to authentificate users with saml provider and everythin was working fine with the redhat 6 and apache 2.2 After the upgrade I am getting the following error when I am trying to open the trac web context url: authz_core:error AH01627: AuthType configured with no corresponding authorization directives and I am getting a 500 Error. The Mellon mod was configured using the redhat manual. I am guessing that I need to adapt some apache 2.4 config here? Thanks in advance.
