Working with Forms
Digital Signature Fields
A digital signature field allows you to lock specific fields on a form using a
password. This authenticates a form and protects its data from unauthorized
modification. For example, an expense report form might require a signature. Once
“signed,” certain fields on the form such as expensed items might be locked. You
can only unlock fields and change the data in them if you have the correct password.
Digital signature fields can be set up to work with OmniForm passwords or with a
more secure level of protection provided by an outside authentication service
(Entrust or Microsoft PKI). Check with the form designer or database
administrator for information about how the digital signatures were set up on a
form.

To sign a digital signature field on a form:
1. Click the signature field.
A dialog box appears and prompts you to enter your username and password.
If it is an OmniForm signature field, make sure you have access to the
appropriate OmniForm database.
The dialog box that appears depends on the type of signature field it is. This
example shows the dialog box for an OmniForm signature field. If the digital
signature field type is Entrust or Microsoft PKI, please refer to their
documentation for more information on how they work.
2. Enter your user name and password.
3. Click OK.
To unsign a signature field, click it and enter your password again.
Note
After a signature field is signed, that form’s design becomes locked. All
records must be unsigned before the form design can be changed. Or,
save the form with a different name, and delete all of its records.
