Please Help...Errors with Samba and LDAP

I am trying to setup a Samba-LDAP-DNS PDC on a Debian Sarge System

the main error I get is when I try the command

net getlocalsid

it gives me this error

[2007/01/12 01:07:12, 0] lib/smbldap.c:smbldap_open_connection(677)
Failed to issue the StartTLS instruction: Connect error

if I look into my /var/log/samba/log.smbd it says

[2007/01/12 01:07:12, 0] lib/smbldap.c:smbldap_open_connection(677)
Failed to issue the StartTLS instruction: Connect error
[2007/01/12 01:07:21, 0] passdb/pdb_ldap.c:ldapsam_search_one_group(1971)
ldapsam_search_one_group: Problem during the LDAP search: LDAP error: (unknown) (Timed out)

This is the first error I get...

The second error I need to fix is in my /var/log/syslog it says...

Jan 12 15:17:01 green CRON[6076]: pam_ldap: error trying to bind (Invalid credentials)
Jan 12 15:17:01 green /USR/SBIN/CRON[6077]: (root) CMD ( run-parts --report /etc/cron.hourly)


Please help I do not know where to start to fix these errors...

Thank You so much in advance
