Description: Maps any of the following fields using the
corresponding mapping algorithms:

|------------+----------------------------|
| Type       | Algorithm                  |
|------------+----------------------------|
| rfc822Name | snmpTlstmCertSANRFC822Name |
| dNSName    | snmpTlstmCertSANDNSName    |
| iPAddress  | snmpTlstmCertSANIpAddress  |
|------------+----------------------------|

The first matching subjectAltName value found in the
certificate of the above types MUST be used when
deriving the tmSecurityName.  The mapping algorithm
specified in the 'Algorithm' column MUST be used to
derive the tmSecurityName.

This mapping results in a 1:1 correspondence between
subjectAltName values and tmSecurityName values.  The
three sub-mapping algorithms produced by this
combined algorithm cannot produce conflicting
results between themselves.
