In the process of setting up a Samba 3.0.14a PDC using OpenLDAP 2.2.23-5 and
smbldap-tools-0.9.1-1 on Fedora Core 4, I encountered a problem.

When starting smbd, it's unable to bind to the LDAP server, while all other
software can (ldapbrowser, ...).  Even when I use smbpasswd to change a current
users' password, it binds to the LDAP server succesfully.

I used Ethereal to capture the packets that are sent between them and I came to
the following conclusion :

When samba tries to bind while starting up, it sends the password with \n after it.

<snip from ethereal capture>

LDAP Message, Bind Request
   Message Id: 1
   Message Type: Bind Request (0x00)
   Message Length: 44
   Response In: 13
   Version: 3
   DN: cn=Manager,dc=EXAMPLE,dc=COM
   Auth Type: Simple (0x00)
   Password: secret\n


This isn't the case when I use ldapbrowser or smbpasswd to access ldap, in those
cases, the password is sent correctly without the \n.

Is this because of smbpasswd -w secret <enter> ?
