Security settings
Security settings control document security by configuring digital IDs, passwords, certificates, and Adobe LiveCycle
Rights Management (ALCRM) servers. Content security settings also control features that affect application behavior
in signing and certificate security workflows.
Set up a roaming ID account
A roaming ID is a digital ID that is stored on a server and can be accessed by the subscriber. You must have an Internet
connection to access a roaming ID and an account from an organization that supplies roaming digital IDs.
1 Do one of the following:
• In Acrobat, choose Tools > Sign & Certify > More Sign & Certify > Security Settings.
• In Reader, choose Edit > Protection > Security Settings.
Note: If you don’t see the Sign & Certify or Protection panel, see the instructions for adding panels at “Task panes” on
page 8
2 Expand Digital IDs on the left, select Roaming ID Accounts, and click Add Account.
3 Type the name and URL for the roaming ID server, and click Next.
4 Type your user name and password or follow the directions to create an account. Click Next, and then click Finish.
Once the roaming ID is added, it can be used for signing or encryption. When you perform a task that uses your
roaming ID, you’re automatically logged in to the roaming ID server if your authentication assertion hasn’t expired.
PKCS#12 modules and tokens
You can have multiple digital IDs that you use for different purposes, particularly if you sign documents in different
roles or using different certification methods. Digital IDs are usually password protected. They can be stored on your
computer in PKCS #12 file format. Digital IDs can also be stored on a smart card, hardware token, or in the Windows
certificate store. Roaming IDs can be stored on a server. Acrobat includes a default signature handler that can access
digital IDs from various locations. Register the digital ID in Acrobat for it to be available for use.
Directory servers
Directory servers are commonly used as centralized repositories of identities within an organization. The server acts
as an ideal location to store user certificates in enterprises that use certificate encryption. Directory servers let you
locate certificates from network servers, including Lightweight Directory Access Protocol (LDAP) servers. After you
locate a certificate, you can add it to your list of trusted identities so that you don’t have to look it up again. By
developing a storage area for trusted certificates, you or a member of your workgroup can facilitate the use of
encryption in the workgroup.
