  • EZproxy

Here are the steps for fixing the error message:

  1. If you recently updated your metadata file and replaced it in the EZproxy root directory, you must ensure it is Case-Sensitive.    
  2. An example would be FederationMetadata.xml must be FederationMetadata.xml and not federationmetadata.xml because they are different.
  3. Have someone sign in to make sure that it is working.
