2.2 Prerequisites

IMPORTANT:Check the currently installed NetIQ and Third Party applications to determine if those products are supported on eDirectory 8.8 before upgrading your existing eDirectory environment. The prerequisites for other NetIQ products can be found on the NetIQ Documentation site. We also recommend you back up an eDirectory instance before performing any upgrades on that instance.

  • (Conditional) Novell International Cryptographic Infrastructure (NICI) 2.7 and eDirectory 8.8 support key sizes up to 4096 bits. If you want to use a 4 KB key size, every server must be upgraded to eDirectory 8.8. In addition, every workstation using the management utilities, for example, iManager must have NICI 2.7 installed on it.

    When you upgrade your Certificate Authority (CA) server to eDirectory 8.8, the key size will not change but will still be 2 KB. The only way to create a 4 KB key size is recreate the CA on an eDirectory 8.8 server. In addition, you would have to change the default from 2 KB to 4 KB for the key size, during the CA creation.

    When you install eDirectory, the nds-install utility automatically installs NICI. For more information about installing eDirectory, see Section 2.6.2, Using the nds-install Utility to Install eDirectory Components. However, if you need to install only NICI, and not eDirectory itself, on a workstation that has the management utilities installed, you must install NICI manually. For more information about manually installing NICI, see Installing NICI.

  • Service Location Protocol (SLP) installed and configured

    With eDirectory 8.8, SLP does not get installed as part of the eDirectory installation.

    Only a root user can install SLP.

    For more information on installing SLP, refer to Using SLP with eDirectory.

  • The Linux host enabled for multicast routing

    To check if the host is enabled for multicast routing, enter the following command:

    /bin/netstat -nr
    

    The following entry should be present in the routing table:

    224.0.0.0 0.0.0.0
    

    If the entry is not present, log in as root and enter the following command to enable multicast routing:

    route add -net 224.0.0.0 netmask 240.0.0.0 dev interface
    

    The interface could be a value such as eth0, hme0, hme1, or hme2, depending on the NIC that is installed and used.

    For more information on multicast and broadcast routes, refer to the OpenSLP Web site.

  • Network server time synchronized

    Use Network Time Protocol's (NTP) ntp to synchronize time across all network servers.

  • (Conditional) If you are installing a secondary server, all the replicas in the partition that you install the product on should be in the On state.

  • (Conditional) If you are installing a secondary server into an existing tree as a non-administrator user, create a container and then partition it. Ensure that you have the following rights:

    • Supervisor rights to this partition.

    • All Attributes rights: read, compare, and write rights over the W0.KAP.Security object.

    • Entry rights: browse rights over Security container object.

    • All Attributes rights: read and compare rights over Security container object.

  • (Conditional) If you are installing a secondary server into an existing tree as a non-administrator user, ensure that at least one of the servers in the tree has the same or higher eDirectory version as that of the secondary being added as container admin. In case the secondary being added is of later version, then the schema needs to be extended by the administrator of the tree before adding the secondary using container admin.

  • While configuring eDirectory, you must enable SLP services and a NetWare Core Protocol (NCP) port (the default is 524) in the firewall to allow the secondary server addition. Additionally, you can enable the following service ports based on your requirements:

    • LDAP clear text - 389

    • LDAP secured - 636

    • HTTP clear text - 8028

    • HTTP secured - 8030

    In case, if you have enabled user-defined ports, you must mention these ports while configuring eDirectory.

    NOTE:This step is required only if you have SLP configured in your system.

  • Do not set the user-defined ports to 8008 and 8010 while upgrading eDirectory 8.8 SP2 or later versions to 8.8 SP8. If the ports are set to 8008 or 8010, ndsconfig assumes that the server is a pre-eDirectory 8.8x server and automatically resets them to 8028 and 8030 respectively.

  • During eDirectory upgrade, if SecretStore has not already been configured with the previous versions, or you do not want to configure SecretStore, use the -m no_ss option with the nds-install utility.

Configuring Static IP Address

Static IP address must be configured on the server for the eDirectory to perform efficiently. Configuring eDirectory on the servers with DHCP address can lead to unpredictable results.
