A user trying to login to Vault using Single Sign-On (SSO) is receiving an Error: Assertion is Missing the uid Attribute.
The SAML Response from the Identity Provider does not include a uid attribute, which is required as it is used to identify the user in Vault.
Configure the Identity Provider to include a uid attribute in the SAML Response to Vault. This attribute should hold the Vault user's username or Federated ID based on how the SAML Profile is configured in Vault.
