Use a SharpHoundCommon revision that defines the DMSA contract.

The cited SharpHoundCommon commit d975701 does not define Label.DMSA or LDAPProperties.ManagedAccountPrecededByLink. It also does not define DataType.DMSAs, which src/Runtime/OutputWriter.cs uses at Line 67. The DMSA changes cannot compile against that revision. Update the common-library dependency to one that provides these symbols, then check both the local and default builds. (raw.githubusercontent.com)

Review comment at @src/Runtime/ObjectProcessors.cs around lines 140 - 141:
Update the SharpHoundCommon dependency revision to one that defines Label.DMSA,
LDAPProperties.ManagedAccountPrecededByLink, and DataType.DMSAs, so
ProcessDMSAObject and the related output code compile. Verify both local and
default builds against the updated revision.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr

Confirmed. The default build resolves the published 4.9.2-dev.* package, which cannot contain the new DMSA contract until SharpHoundCommon #321 merges into v4 and Publish Dev Package completes. The local build against sibling Common head 09344aa compiles with 0 errors. I am keeping this thread open; after that package is published I will update the dependency revision and rerun both default and local builds.

@adilalperenciftci Understood. Your reported local build against 4e182d3 supports compatibility with that Common revision, but does not verify the published-package build. This finding remains open pending package publication, the dependency update, and successful default and local builds.
