If your daughter was signed-in to iCloud with her own AppleID (this presumably being associated with an employer's email address), should the AppleID credentials have been forgotten, you may now have a problem.
If the iPad disabled or Activation Locked, unless you can recover access to the AppleID account the iPad is (and will remain) useless to you.
Here are the Apple support pages that outline the Activation Lock - and the only mechanisms by which it can be satisfied:
Activation Lock for iPhone, iPad, and iPod touch - Apple Support
Turn off Activation Lock – Apple Support
If the AppleID or associated password have been forgotten, they can be recovered here:

To recover your credentials, you’ll need access to any one of the following:
- Your primary email address mailbox that corresponds with your AppleID
- Any of the secondary/recovery email addresses that should be configured for your AppleID account
- Any of the trusted telephone numbers (fixed line or Cellular/Mobile) that are associated with your AppleID
