Owner's Manual

When installing the DSET or collecting DSET report using DSET version 3.5.0 and earlier, you must enter password at
the command line interface on systems running Linux. If the credentials are correct and the CIMOM (SFCB or
OpenPegasus) authenticates, the installation or report collection process is successfully completed.
From DSET version 3.5.1 and later, DSET supports single sign-on for the logged-in user. That is, DSET does not
anymore require a password for its functioning. CIMOM accepts a client certificate while establishing the HTTPS
connection. If the certificate is signed by a trusted authority, a network connection is started. During installation,
DSET generates and deploys its own certificate and key which is used later. The access to these files is limited only
to the root user.
A brief description about the DSET installation or report collection process:
1. Collecting DSET report without providing any username or password: DSET tries for CIMOM connections
through certificates.
1. If the connection is successful, the report collection continues without prompting for a password.
2. If the connection is unsuccessful, DSET asks whether or not you want to provide password and
continue.
If you choose to continue, DSET prompts you to enter root password and
proceed.
If you decide not to proceed, credential-based authentication is not performed.
2. Collecting DSET report by providing username and/or password, DSET will not try for a certificate-based
connection and prompts for a password (if not entered).
Note: The tasks mentioned earlier in Credential-less CIMOM Authentication On Systems Running Linux section are
also applicable for DSET installation only when CIMOMs are pre-installed and operational.
Possible Reasons For Unsuccessful Certificate Connection
The following are the possible reasons for unsuccessful certificate connection:
DSET client certificate has expired. By default, the certificate is valid for one year from the time
of generation.
A particular version of operating system or CIMOM does not support certificate-based
Authentication.
DSET does not perform the certificate-based connections because there are known issues with
a particular version of operating system or CIMOM for certificate-based authentication.
DSET client certificate or CIMOM Trust Store is corrupted.
Limitations
The following are the limitations:
The credential-less authentication does not work on ESX. Therefore, DSET requires the
credentials to run on ESX.
For credential-less authentication, the minimum supported version of Tog-pegasus is 2.11.0 and
that of SFCB is 1.3.11. In case, the server has CIMOM versions earlier than the versions specified,
you will be prompted for a password.
Installation Instructions
For instructions on installation, advanced command-line installation, and error codes refer to the DSET
Installation Guide.
