Thanks a lot for this wonderful post. This was one of the few places I found this help. I did add a login (via spring security) to my spring cloud config server (with credentials stored in a database). However, it is not possible for me to load the property sources for config clients when I store the username and password for the clients on vault (using the secret path). Any advice on how to deal with this issue? I do not want to hard code the username and password for each config client to fetch properties from the config server. Thanks again.
