OK, the above tells you what the error is

The above shows you where it is coming from

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

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