      This ticket is related to https://jira.mongodb.org/browse/SERVER-51651.

      We are going to run atlas proxy with mongodb 4.9+ version in the future. While trying to run the test harness with a new mongod in dev, I found a breaking change.

      We depend on the `rolesInfo` command to load the roles we are interested in. With the current command params, 4.9 doesn’t populate `inheritedPrivileges` which we use and doesn’t include the `isBuiltin` field.

      Binaries we were using for testing:
      Enterprise MacOS: https://mciuploads.s3.amazonaws.com/mongodb-mongo-master/enterprise-macos/d7da6ab29e45b3ab22652e12bb524d966511ebf8/binaries/mongo-mongodb_mongo_master_enterprise_macos_d7da6ab29e45b3ab22652e12bb524d966511ebf8_20_10_24_03_38_42.tgz
      Enterprise RHEL 7.0: https://mciuploads.s3.amazonaws.com/mongodb-mongo-master/enterprise-rhel-70-64-bit/d7da6ab29e45b3ab22652e12bb524d966511ebf8/binaries/mongo-mongodb_mongo_master_enterprise_rhel_70_64_bit_d7da6ab29e45b3ab22652e12bb524d966511ebf8_20_10_24_03_38_42.tgz

      Code to reproduce the bug:

      arr = [];
      arr.push({role: "backup", db: "admin"});
      arr.push({role: "clusterMonitor", db: "admin"});
      arr.push({role: "dbAdmin", db: "admin"});
      arr.push({role: "dbAdminAnyDatabase", db: "admin"});
      arr.push({role: "enableSharding", db: "admin"});
      arr.push({role: "read", db: "admin"});
      arr.push({role: "readAnyDatabase", db: "admin"});
      arr.push({role: "readWrite", db: "admin"});
      arr.push({role: "readWriteAnyDatabase", db: "admin"});
      arr.push({role: "readWrite", db: "eliot1-test"});
      arr.push({role: "dbAdmin", db: "eliot1-test"});
      arr.push({role: "read", db: "eliot1-test2"});
      arr.push({role: "dbAdmin", db: "eliot1-test2"});
      arr.push({role: "readWrite", db: "eliot1-timTest"});
      arr.push({role: "readWrite", db: "no-limits-test"});
      arr.push({role: "dbAdmin", db: "no-limits-test"});
      arr.push({role: "read", db: "no-limits-test2"});
      arr.push({role: "dbAdmin", db: "no-limits-test2"});
      arr.push({role: "readWrite", db: "no-limits-timTest"});
      res = db.adminCommand({rolesInfo: arr, showBuiltinRoles: 1, showPrivileges: 1})
      printjson(res)
      

      The output for 4.4 and 4.9+ is attached in the comments for comparison.
