System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP)

Creating a Checklist Based on Your Server Installation

During the server installation process, you will have defined crucial variables, with which you should create a checklist similar to the one below before launching idsconfig. You can use the blank checklist provided in Blank Checklists.

Note –

The information included below will serve as the basis for all examples that follow in the LDAP related chapters. The example domain is of an widget company, Example, Inc. with stores nationwide. The examples will deal with the West Coast Division, with the domain west.example.com

Table 11–1 Server Variables Defined


Variable	Definition for Example Network
Port number at which an instance of the directory server is installed	389 (default)
Name of server	`myserver` (from the FQDN myserver.west.example.com or 192.168.0.1)
Replica server(s) (IPnumber:port number)	`192.168.0.2` [for myreplica.west.example.com]
Directory manager	cn=directory manager (default)
Domain name to be served	`west.example.com`
Maximum time (in seconds) to process client requests before timing out	`-``1``-`
Maximum number of entries returned for each search request	`-``1``-`

Note –

If you are using hostnames in defining defaultServerList or preferredServerList, you MUST ensure LDAP is not used for hosts lookup. This means ldap must not be in /etc/nsswitch.conf hosts line.

Table 11–2 Client Profile Variables Defined


Variable	Definition for Example Network
Profile name (the default name is default)	`WestUserProfile`
Server list (defaults to the local subnet)	`192.168.0.1`
Preferred server list (listed in order of which server to try first, second, and so on)	`none`
Search scope (number of levels down through the directory tree. '`One`', the default, or '`Sub`')	`one` (default)
Credential used to gain access to server. Default is `anonymous`	`proxy`
Follow Referrals? ( a pointer to another server if the main server is unavailable) Default is `no`.	`Y`
Search time limit (default is 30 seconds) for waiting for server to return information.	`default`
Bind time limit (default is 10 seconds) for contacting the server.	`default`
Authentication method Default is `none`.	`simple`

Note –

Client profiles are defined per domain. At least one profile must be defined for a given domain.

Attribute Indexes

idsconfig indexes the following list of attributes for improved performance.

membernisnetgroup: pres,eq,sub
nisnetgrouptriple: pres,eq,sub
ipHostNumber: pres,eq,sub
uidNumber: pres,eq
gidNumber: pres,eq
ipNetworkNumber: pres,eq
automountkey: pres,eq
oncRpcNumber: pres,eq
