# Enable SSL in LDAP authentication \[Updated in Security Center 1.5 and 2.0\]

Manage the encryption of LDAP authentication requests on your instance.

Use the **glide.ldap.use.ssl** property to enable or disable TLS encryption for LDAP authentication requests sent over the network. If this property is not set to the recommended value of **true**, LDAP authentication is susceptible to a man-in-the-middle attack.
