@rahuldutta90 Hey Rahul, would you mind taking a look at this PR that we are looking to get into the breaking change release?

@hosunmsft can you please review the ADLA changes?

@maddieclayton Hi Maddie, I see this change is related to the CatalogSecret, can you elaborate a bit on why we need this change?

[maddieclayton]

@hosunmsft I removed the CatalogSecret cmdlets because they currently have an obsolete warning saying that they will be removed in the next breaking change release (https://github.com/Azure/azure-powershell/pull/8078/files#diff-4e1f7756e0e00564e395906d53a747d4L24). Is this incorrect?
