Vault and Vault Enterprise’s (“Vault”) ldap auth method may not have correctly enforced MFA if username_as_alias was set to true and a user had multiple CNs that are equal but with leading or trailing spaces. Fixed in Vault Community Edition 1.20.2 and Vault Enterprise 1.20.2, 1.19.8, 1.18.13, and 1.16.24.
