Oracle Fusion Middleware Administration Guide for Oracle Directory Server Enterprise Edition

Examples of the ldapsearch Command

You can perform DIGEST-MD5 client authentication without using SSL. The following example uses the default DIGEST-MD5 identity mapping to determine the bind DN:

$ ldapsearch -h host1 -p 1389 \
 -o mech=DIGEST-MD5 [ \
 -o realm=""] \
 -o authid="dn:uid=bjensen,dc=example,dc=com" \
 -w - \
 -o authzid="dn:uid=bjensen,dc=example,dc=com" \
 -o secProp="minssf=56,maxssf=256,noplain" \
 -b "dc=example,dc=com" "(givenname=Richard)"

The preceding example shows the use of the -o (lowercase letter o) option to specify SASL options. The realm is optional, but if specified, it must be the fully qualified domain name of the server host machine. The authid and authzid must both be present and identical, although the authzid intended for proxy operations is not used. The -w password option applies to the authid.

The value of authid is the Principal used in identity mapping. The authid should contain either the dn: prefix followed by a valid user DN in the directory, or the u: prefix followed by any string determined by the client. This use of authid allows you to use the mappings that are shown in DIGEST-MD5 Identity Mappings.

The most common configuration is for an SSL connection to provide encryption over the LDAPS secure port and DIGEST-MD5 to provide the client authentication. The following example performs the same operation over SSL:

$ ldapsearch -h host1 -P 1636 \
 -Z -P .mozilla/bjensen/BJE6001.slt/cert8.db \
 -N "cert-example" -w - \
 -o mech=DIGEST-MD5 [-o realm=""] \
 -o authid="dn:uid=bjensen,dc=example,dc=com" \
 -o authzid="dn:uid=bjensen,dc=example,dc=com" \
 -o secProp="minssf=0,maxssf=0,noplain" \
 -b "dc=example,dc=com" "(givenname=Richard)"

In this example, the -N and -w options are required by the ldapsearch command, as the operation is performed over SSL. However , these options are not used for client authentication. Instead, the server performs another DIGEST-MD5 identity mapping of the Principal in the authid value.
