The default admin account is always authenticated locally, regardless of the authentication method
setting. (See
Chapter 31 on page 400 for more information about authentication methods.)
The ZyWALL fails to authentication the ext-user user accounts I configured.
An external server such as AD, LDAP or RADIUS must authenticate the ext-user accounts. If the
ZyWALL tries to use the local database to authenticate an ext-user, the authentication attempt will
always fail. (This is related to AAA servers and authentication methods, which are discussed in
Chapter 31 on page 400 and Chapter 32 on page 409 , respectively.)
I cannot add the admin users to a user group with access users.
You cannot put access users and admin users in the same user group.
I cannot add the default admin account to a user group.
You cannot put the default admin account into any user group.
The schedule I configured is not being applied at the configured times.
Make sure the ZyWALL’s current date and time are correct.
I cannot get a certificate to import into the ZyWALL.
1
For My Certificates, you can import a certificate that matches a corresponding certification
request that was generated by the ZyWALL. You can also import a certificate in PKCS#12 format,
including the certificate’s public and private keys.
2
You must remove any spaces from the certificate’s filename before you can import the certificate.
3
Any certificate that you want to import has to be in one of these file formats:
• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters,
uppercase letters and numerals to convert a binary X.509 certificate into a printable form.
• Binary PKCS#7: This is a standard that defines the general syntax for data (including digital
signatures) that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The
private key is not included. The ZyWALL currently allows the importation of a PKS#7 file that
contains a single certificate.
