LDAP SASL, or Simple Authentication and Security Layer for LDAP, is a framework providing a unified way to authenticate clients to LDAP servers using various security mechanisms, such as Kerberos, GSSAPI, or PLAIN.
GSSAPI, or the Generic Security Services API, is a standardized framework that provides a way for applications to access security services, like authentication, in a mechanism-independent manner.

priority = 0
weight = 100
port = 88
svr hostname = 7-dev-de-dc16.other.local
7-dev-de-dc16.other.local internet address = 10.15.7.16
