Bitbucket: move or use users from AzureAD instead of local directory

[Alexander]

Hello,

i want our users to come from AzureAD instead of the local, which were created a long time ago. I already use AzureAD within Atlassian Admin and Confluence.

I have some questions:

1. How do i do that?
2. If the user is changed to AzureAD, will the repository access be changed by that?
3. Is it easier to use groups instead of induvidual access rights?

Many thanks for help

Alexander
