The LDAP-based directory service was made available in January 15, 2001. AIT (Applied Information Technology), the group that was responsible for LDAP before Identity Services, implemented LDAP as a replacement for the Ph directory server, ph.psu.edu. While Ph had served the University community well, the international technical community has created LDAP as a standardized way for exchanging such information. This enables new services at Penn State while making it easier to locate contact information of friends and colleagues at other institutions.
Before LDAP, directories at every higher education institution were different. Difficulty arose when a person at one institution attempted to get meaningful information, such as email addresses, from another institution without prior knowledge of the directory of the other institution. The eduPerson definition was defined by EDUCAUSE, a consortium of higher education institutions, to provide a means of universal information exchange among higher education institutions. This follows existing federal and state privacy laws and includes mechanisms for individuals to request their information be withheld. In addition, much attention has been given to ensure Penn State policies are adhered to.
PH to LDAP Gateway
PH queries will continue to be supported through a PH-to-LDAP gateway. When making a request to PH, from either a client or from the Penn State Online Directory, the bridge will make the request to LDAP and return the results to the user in a format the Ph program can understand.
Such Ph commands would be similar to:
ph -s ph.psu.edu query alias=xyz5000
