When test ldapbind, sometime bind succeed, sometime fail.

$ ./ldapbind -h <OID_HOSTNAME> -p <OID_PORT> -D '<OID_USER_DN>' -w <USER_PASSWORD_FROM_AD>
ldap_bind: Strong authentication required
ldap_bind: additional info: 00002028: LdapErr: DSID-0C09032E, comment: The server requires binds to turn on integrity checking if SSL\TLS are not already active on the connection, data 0, v4f7c

$ ./ldapbind -h <OID_HOSTNAME> -p <OID_PORT> -D '<OID_USER_DN>' -w <USER_PASSWORD_FROM_AD>
bind successful

$ ./ldapbind -h <OID_HOSTNAME> -p <OID_PORT> -D '<OID_USER_DN>' -w <USER_PASSWORD_FROM_AD>
ldap_bind: Strong authentication required
ldap_bind: additional info: 00002028: LdapErr: DSID-0C09032E, comment: The server requires binds to turn on integrity checking if SSL\TLS are not already active on the connection, data 0, v4f7c
