Help Implementing Two-factor Authentication
We would like to implement two-factor authentication, particularly Duo Security (www.duosecurity.com). We have LDAP and Duo will be another layer of authentication, in addition to that.
Our company has Duo Security for other websites and if we could, we would like to use the same vendor in our HR system. After getting authenticated in LDAP, it will challenge the user by sending a key/code to a registered mobile number (or call) and user has to enter it on an iFrame from Duo, and will be authenticated accordingly. Duo provides the code, in certain languages (e.g. Java, Python, etc), and essentially add those codes to the existing system upon signon and it should work.
