This feature is new in the Solaris 9 12/02 release.
The Solaris installation programs now support LDAP Version 2 profiles. These profiles enable you to configure your system to use a proxy credential level. During the Solaris Web Start or suninstall programs, you can specify the LDAP proxy-bind distinguished name and proxy-bind password. With any installation method, you can preconfigure LDAP before installation by using the proxy_dn and proxy_password keywords in the sysidcfg file.
For information, see the Solaris 9 9/04 Installation Guide.
