How can we reproduce the problem in the simplest way?

1. azcopy login
2. Run command as above with two shares

Continue using SAS tokens.

Hi @mbrat2005, sorry. The error is misleading. Azure Files does not yet support using Identity or other forms of oAuth yet. Use a SAS token on both source and destination.

[mbrat2005]

It would be great if the error were more clear, but even better if AzCopy supported identity based file sync--especially with more customers moving to further secure their Storage Account by disabling key-based auth.

This should be fixed in 10.20.0. Thanks for your patience while we got the release out!
