How to use IE11 and Pop-Up Window Support for CDMS SSO Authentication in Vault?
If using IE11 and SSO, the Authenticate SAML eSignatures in a pop-up window rather than an iFrame feature must be enabled. Navigate to: Admin --> Settings --> Domain Settings --> SAML Profiles.
Note: Veeva recommends moving away from using IE11, as this is deprecated in the 22R1 General Release.
