ZyXEL Communications NXC2500 User Manual page 379

An external server such as AD, LDAP or RADIUS must authenticate the ext-user accounts. If the
NXC tries to use the local database to authenticate an ext-user, the authentication attempt will
always fail.
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 NXC's current date and time are correct.
I cannot get a certificate to import into the NXC.
For My Certificates, you can import a certificate that matches a corresponding certification
1
request that was generated by the NXC. You can also import a certificate in PKCS#12 format,
including the certificate's public and private keys.
You must remove any spaces from the certificate's filename before you can import the certificate.

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 NXC currently allows the importation of a PKS#7 file that
contains a single certificate.
• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase
letters, uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable
form.
• Binary PKCS#12: This is a format for transferring public key and private key certificates.The
private key in a PKCS #12 file is within a password-encrypted envelope. The file's password is not
connected to your certificate's public or private passwords. Exporting a PKCS #12 file creates this
and you must provide it to decrypt the contents when you import the file into the NXC.
