Description
Post upgrade of firmware to 12.4 users connecting with Windows 7 fail to Authenticate or Negotiate.
Cause
Windows 7 user older SSL Encryption as 12.4 is designed to support with TLS 1.2 and above
Resolution
SMA1000 had provisioned to support better SSL Encryption for secured communication:
Below Categories have been provisioned or updated on 12.4: Management Console-SSL Settings-SSL Encryption:
- Modern to support only TLS 1.3.
- Secure (Default) Supports TLS 1.2 and above.
- Legacy Adds support for older ciphers that are no longer considered secure
We would need to Change Encryption to Legacy for supporting Windows 7.
Note: These would have weaker encryption and have been categorized for administrators to choose for supporting older client versions.
