When you test the connection to the server, your NetMRI-to-LDAP server connections (or for Active Directory connections) allow for loading a current SSL certificate from a .PEM file. See the section *[NetMRI Security Settings](https://infoblox-docs.atlassian.net/wiki/spaces/netmri754/pages/193430194)* for the process of adding SSL certificates to NetMRI. This certificate automatically appears in the authentication server’s **Certificate** drop-down menu after being loaded into NetMRI.

An LDAP connection test shows the following:

`Username: ******`  
`Password:******`  
`Process Started`

`2015-05-01 17:41:59 ------------------------------------------------------`  
`Authentication Test Completed`

If you set the **Encryption** menu to **None**, this option remains unavailable, and authentication tests will show a blank `certPath` value in the test output.
