What is the significance of the `domainname` field in the `aaalogin` table for encryption analysis?

The `domainname` field distinguishes between domain users and custom users. When `domainname` equals 'ADAudit Plus Authentication', the account is a custom user. For domain users, the encryption uses a default password ('admin'), making their hashes potentially weaker. The salt field in the `aaapassword` table is irrelevant; the salt is embedded in the hash itself. This distinction is critical for targeted brute-force attacks, as highlighted in the ADAudit Plus Exploitation Analysis — Data Encryption Analysis.
