In order to use the Web interface to change or delete an existing entry in the Host Database, at least one of the Technical Contacts listed in that database entry must be an email address of the form: firstname.lastname@example.org, where netid is an OIT netid.
After at least one of the Technical Contacts meets that requirement, you will be able to use the Web interface to make changes to that entry.
When you enter the Web interface, you are prompted for a netid and password. You must enter an OIT netid that is part of an email address that meets the requirement above. You must enter that netid's LDAP password.
The upshot is that when registering new devices in the Host Database, it is a very good idea if you specify at least one Technical Contact that meets one of the requirements above. That way in the future, that person will be able to use the Web to manipulate the resulting Host Database entry.
If you already have a host registered that doesn't meet that requirement, you may wish to submit a change request so it has at least one Technical Contact that meets that requirement. (Naturally, that change request won't be possible via the Web; you will have to email your request it to email@example.com . Be sure to send the email from one of the email addresses currently listed as a Technical Contact!)
If you need to specify a mailing list as a Technical Contact, then it is possible for Hostmaster to set things up so any of a small list of users will be treated as authorized to change the Host Database entry that lists this mailing list as a Technical Contact. Contact firstname.lastname@example.org for assistance.
Do not specify an email alias address (for example, email@example.com) as a Technical Contact. Doing so will prevent that customer from being able to use the Web to change or delete the Host Database entry. This is because the customer must still login to the Host Database Web site using the customer's netid and password, and that netid is not the same as nickname.
Note that other people are also authorized to change or delete existing Host Database entries. Host Database Departmental Contacts associated with the entry's DEPARTMENT are authorized to change or delete the entry. And a small number of OIT staff are authorized to change or delete existing entries; those Host Database Trusted Parties are OIT staff members who are sometimes responsible for acting on behalf of customers throughout the University.
