2. Log on to the server with an account that has administrative privileges.
3. Run regedit as Administrator.
4. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> Wow6432Node >> Tanium >> Tanium Server.
5. Validate the value for REG_DWORD "ForceSOAPSSLClientCert" is set to "1".
6. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> Wow6432Node >> Tanium >> Tanium Server.
7. Validate the following keys exist and are configured:
REG_SZ "ClientCertificateAuthField"
For example:

REG_SZ "ClientCertificateAuthRegex"
For example-DoD:
.+?Name:\s*?(\S+@[._a-zA-Z0-9]+).*
