[nssldap] Rebind code is nss_ldap with TLS selected

[Howard Wilkinson <howard [at] cohtech.com>]

I am currently doing some mods the the ldap-nss.c code in 264 prior to 
enhancing the reconnect code. There is a facility in the code to support 
'rebinding' This is implemented by the do_rebind function.

Unlike do_open this code does not call 'do_ssl_options' before issuing 
the 'do_start_tls' operation. Does anybody know if this is by design or 
is this an oversight.

Regards, Howard.
