[Samba] Samba NT4 to AD- LDAP

[Praveen Ghimire]

Hi Rowland,

I did that initially and that came with 
Failed to connect to ldap URL 'ldap://lin-pdc.lin - LDAP client internal error: NT_STATUS_BAD_NETWORK_NAME
Hence I removed the whole ldap:// bit

After your email I tried again but using ldap://localhost and it seems to have worked. Not sure what the issue is with the fqdn. I could run ldap queries when using fqdn.


Regards,

Praveen Ghimire

OK, the above tells you what the error is

The above shows you where it is coming from 

>   passdb backend = ldapsam

Because of the above ;-)

If you look closely at what fails:

samba3.lp.get("passdb backend").split(":",1)[1].strip('"')

It takes the 'passdb backend' line and tries to split it at the ':'
character and then removes any ' " '

Now you know what is wrong, how to fix it ?

In the short term, try changing the 'passdb backend' line in smb.conf to
this:

passdb backend = ldapsam:"ldap://lin-pdc.lin/"
