ldap_sasl_authid (string)

           Specify the SASL authorization id to use. When GSSAPI/GSS-SPNEGO are used, this represents the Kerberos principal used for authentication to

           the directory. This option can either contain the full principal (for example host/myhost@EXAMPLE.COM) or just the principal name (for

           example host/myhost). By default, the value is not set and the following principals are used:

               hostname@REALM

               netbiosname$@REALM

               host/hostname@REALM

               *$@REALM

               host/*@REALM

               host/*

           If none of them are found, the first principal in keytab is returned.

           Default: host/hostname@REALM
