2.4 Authentication Mechanism
OMPC uses Basic Authentication along with HTTPs to enable authentication of REST requests.
Each request requires an Authorization header in the request, in the format of base-64 encoded string of
the combination of following credentials:
 username,
 password,
 accountType: Possible values for this field are:
o OMPC_ACCOUNT = 0;
o WIN_LOCAL_ACCOUNT = 1;
o WIN_DOMAIN_ACCOUNT = 2;
o LINUX_LOCAL_ACCOUNT = 3;
o LDAP_ACCOUNT = 4;
 Domain: It is an optional field unless accountType field value is WIN_DOMAIN_ACCOUNT.
Example:
Name=admin, Password=user@123 and AccountType= OMPC_ACCOUNT, no domain specified.
The combination of username, password, and accountType is admin:user@123:0, and the base-64
encoded string for this combination is YWRtaW46dXNlckAxMjM6MA==
Note:
If the credentials are missing or invalid, a 401 (Authorization failure) error is displayed.
This mechanism is only supported when SSL/TLS is enabled for the transport.
