When the git config file has url settings such as:

[url "ssh://git@myserver.com:7999"]
insteadOf = https://myserver.com:8443/scm

git submodule update still attempts to clone from the https url. I'm using this to try to override the remote URL for specific submodules.

Here's the error message:

Cloning into 'folder/modulename'...
fatal: Authentication failed for 'https://myserver.com:8443/scm/proj/project.git/'
Clone of 'https://myserver.com:8443/scm/proj/project.git/' into submodule path 'folder/modulename' failed
