User Authentication - Common
Authentication failed
<methodname> authentication failed. Login to account
<loginname> not allowed or account non-existent.
The system administrator has denied logging in for the user, or the user is
trying to log in using a non-existent account.
Authentication failed, user does not exist
User <login-name> does not exist.
Authentication failed because the specified user account does not exist.
Authentication failed, system policy doesn't allow user's
login
User <login-name>'s login is not allowed due to system
policy
Authentication failed because the system policy does not allow the user to log
in. The account may be locked or expired, for example.
Authentication failed, username is on deny list
User <login-name> is denied login because username matched with
deny list.
Authentication failed because the specified user name is included in the
server's deny list.
Authentication failed, username not on allow list
User <login-name> is denied login because allow list exists, and
username was not matched.
Authentication failed because the specified user name is not included in the
server's allow list.
Authentication failed, user's group is on deny list
User <login-name> is denied login because user's group is on
group deny list.
Authentication failed because the user's group is included in the server's group
deny list.
Authentication failed, user's group is not on group allow list
User <login-name> is denied login because group allow list
exists, and user's group didn't match.
Authentication failed because the user's group is not on the server's
group allow list.
Authentication not allowed from a host
<methodname> authentication failed. Connection from <hostname>
denied. Authentication as user <loginname> was attempted.
The server has determined that the user is not allowed to login from the current
host.
Authentication not allowed, unable to reverse map hostname
Login not allowed because host's IP address (<ip-address>) could
not be mapped to a host name and reverse mapping is required.
The server could not map the connecting host's IP address to a
host name and the configuration option RequireReverseMapping is on.
Authentication not allowed, host is on the deny list
Login not allowed because the connecting host (<hostname>) is on
the server's deny list.
The connecting host is on the server's deny list, so the
authentication is not allowed.
Authentication not allowed, host is not on the allow list
Login not allowed because the connecting host (<hostname>) is
not on the server's allow list.
The connecting host is not on the server's allow list, so the
authentication is not allowed.
