Issue/Introduction

Attempting to download files using the Offline Bundle Transfer Utility for SDDC Manager/VCF fails with error: username or password is invalid for user.

Environment

VCF 5.x

Cause

The SSL connection between the OBTU machine and Broadcom is being decrypted and re-encrypted by SSL interception software.

If you view the certificate advertised on the dl.broadcom.com website, it will be signed by a 3rd party internal CA. 

The OBTU does not trust these 3rd party CAs by default, and will need to trust them in order to use the tool properly. 

Resolution

Download the CA certificates that are re-signing the dl.broadcom.com certificate, and import them into the 'cacerts' trust store of the OBTU : 
/opt/obtu/jre/lin64/bin/keytool -importcert -file cacert.cer -keystore /opt/obtu/jre/lin64/lib/security/cacerts
