Discovery policy considerations
If your enterprise configures hosts to lock out access after multiple failed authentication attempts, take the following tips into consideration:
If you choose more than one credential in the Discovery Policy credentials list, you risk host authentication failure lock-out. The discovery process will try the first credentials and if they fail, discovery will try the next credentials that you've selected. Therefore, if your hosts are configured to prevent multiple authentication retries, multiple failed attempts may cause a lock-out.
If multiple Discovery Policies are running simultaneously, with one policy using an IP address to access the host and the other policy using a name to access the host, the multiple access attempts may cause a lock-out. Note that if the authentication attempts are successful, only one host record is added to the inventory.
