One Identity Safeguard for Privileged Sessions 6.9.3 - Administration Guide

VNC is not working with TLS

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.

Configuring the IPMI from the BIOS after losing IPMI password

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.

Prerequisites

To apply the procedure outlined here, you will need physical access to a monitor and keyboard.

To configure the IPMI from the BIOS after losing your IPMI password

1. Shut down SPS.

2. Unplug the SPS physical appliance's power cord.

3. Wait 30 seconds.

4. Replug the power cord.

5. Restart the appliance.

6. Press the DEL button when the POST screen comes up while the appliance is booting.

7. In the BIOS, navigate to the IPMI page.

8. On the IPMI page, select BMC Network Configuration, and press Enter.

   Figure 363: IPMI page > BMC Network Configuration option

   

9. On the BMC Network Configuration page, select Update IPMI LAN Configuration, press Enter, and select Yes.

10. Stay on the BMC Network Configuration page, select Configuration Address Source, press Enter, and select Static.

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

    Figure 366: BMC Network Configuration page > Station IP Address, Subnet Mask, Gateway IP Address

    

12. 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.

Incomplete TSA response received

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.

For details, see Generating TSA certificate with Windows Certificate Authority on Windows Server 2008 or Generating TSA certificate with Windows Certificate Authority on Windows Server 2012.

Using UPN usernames in audited SSH connections

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 test@ema.il 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.
