ME keeps asking for password

[gold2718]

Summary of Issue:

When checking out a repository that needs a password, ME keeps asking for the password even though it has checked out the repository.

Expected behavior and actual behavior:

• Expected: When repository access is required, ME asks for password once
• Actual: ME asks for password, accesses repository, then asks for the password at least two more times.

Steps to reproduce the problem (should include model description file(s) or link to public repository):

Prepare an externals.cfg file with at least one private repository (one that requires a password to clone).
Run checkout_externals
