Consult your LDAP server documentation to generate an SSL certificate forLDAP server authentication. Store the certificate in a file on the NIS+ server(/var/nis/cert7.db, for example) and modify /etc/default/rpc.nisd asfollows.nisplusLDAPTLS=sslnisplusLDAPTLSCertificateDBPath=/var/nis/cert7.dbBe sure to protect the certificate file from unauthorized access. Note that the aboveprovides session encryption and authentication of the LDAP server to the rpc.nisd.It does not provide authentication of the rpc.nisd to the LDAP server, since thecertificate does not contain anything that identifies the LDAP client (rpc.nisd).However, you can combine SSL with another authentication method (simple,sasl/digest-md5) in order to achieve mutual authentication.Performance and IndexingWhen the rpc.nisd daemon is asked to enumerate an NIS+ table (using niscat(1)for example) that is mapped from LDAP, it will enumerate the corresponding LDAPcontainer if at least one entry in the table has an expired TTL. Although this containerenumeration is done in the background, so that LDAP performance is of limitedimportance, it can nevertheless be beneficial to establish LDAP indices to speed upcontainer enumeration for large containers.To obtain an estimate of the amount of time required for enumeration of a particularcontainer, you can use a command like the following.% /bin/time ldapsearch -h server-address -D bind-DN -w password \-b container, search-base ’cn=*’ /dev/nullwhere■■server-addressIP address portion of preferredServerList value from/etc/default/rpc.nisdbind-DNnisplusLDAPproxyUser value from /etc/default/rpc.nisd272 System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP) • January 2005

If this valueexceeds a significant fraction (25 percent or more) of the TTL for the correspondingtable entries (see “Authentication and Security” on page 257), it might be beneficial toindex the LDAP container.The rpc.nisd supports the simple page and VLV indexing methods. Refer to yourLDAP server documentation to find out which indexing methods it supports, and howto create such indices.nisplusLDAPdatabaseIdMappingnisplusLDAPentryTtlnisplusLDAPobjectDNMapping NIS+ Objects Other Than TableEntriesYou can store NIS+ objects other than table entries in LDAP. However, doing so has noparticular value unless you also have NIS+ replicas that obtain those NIS+ objectsfrom LDAP. The recommended choices are the following.■There are no replicas, or the replicas obtain their data from the NIS+ master only.Edit the mapping configuration file (see NIS+LDAPmapping(4)) to remove thefollowing attribute values for all non-table-entry objects.For example, if you started out from the/var/nis/NIS+LDAPmapping.template file, the sections you need to remove(or disable by commenting) are as follows.# Standard NIS+ directoriesnisplusLDAPdatabaseIdMapping...nisplusLDAPdatabaseIdMappingnisplusLDAPdatabaseIdMappingbasedir:user_attr_table:user_attr.org_diraudit_user_table:audit_user.org_dirChapter 16 • Transitioning From NIS+ to LDAP 273
