Some vendors may use custom protocol elements and TLS-encryption that do not have available documentation. As a result, these cannot be audited by One Identity Safeguard for Privileged Sessions (SPS). Regardless of vendors, only the custom features described in the RFC 6143 are supported. As for encryptions, only those completely TLS-encapsulated streams can be processed where the TLS encryption process was started before the VNC protocol handshake.
It may happen that you inadvertently lose the IPMI password of your One Identity Safeguard for Privileged Sessions (SPS). The following procedure describes how you can re-configure your SPS if you lose your IPMI password.
To apply the procedure outlined here, you will need physical access to a monitor and keyboard.
To configure the IPMI interface from the BIOS after losing your IPMI password
Shut down SPS.
Unplug the SPS physical appliance's power cord.
Wait 30 seconds.
Replug the power cord.
Restart the appliance.
Press the DEL button when the POST screen comes up while the appliance is booting.

In the BIOS, navigate to the IPMI page.
On the IPMI page, select BMC Network Configuration, and press Enter.
Figure 328: IPMI page > BMC Network Configuration option
On the BMC Network Configuration page, select Update IPMI LAN Configuration, press Enter, and select Yes.
Figure 329: BMC Network Configuration page > Update IPMI LAN Configuration
Stay on the BMC Network Configuration page, select Configuration Address Source, press Enter, and select Static.

Still on the BMC Network Configuration page, configure the Station IP Address, Subnet Mask, and Gateway IP Address individually.

Press F4 to save the settings, and exit from the BIOS.
About a minute later, you will be able to log in on the IPMI web interface.
When using a TSA certificate generated with Windows Certificate Authority, you might see a similar error message:
Incomplete TSA response received, TSA HTTP server may be responding slowly; errno='Success (0)', timeout_seconds='30'
When generating the certificate, make sure that you do the following:
Optional Key Usage: If Key Usage is present, it must be digitalSignature and/or nonRepudiation. Other values are not permitted. Make sure that in Encryption, Allow key exchange without key encryption (key agreement) is selected.
In Encryption, do NOT select Allow key exchange only with key encryption (key encipherment), because it will result in errors.
When you specify user names in a User Principal Name (UPN) format (e-mail address as username) for an SPS-audited SSH connection, the connection is unsuccessful.
The connection is unsuccessful because SPS uses the '@' character in the username as inband destination selection. If this happens, the username is stripped from the domain part and the UPN suffix is interpreted as inband target. For example, if using email@example.com as username, the username for the connection will be 'test' and the inband destination is 'ema.il'. SPS interprets the last two '@' characters from the connection string, for example, username@my-inband-target@SPS.
To avoid this, you must use inband destination selection. By specifying the target host explicitly, you can prevent SPS to misinterpret the '@' character from UPN usernames.
