No, don't want to bore you with samba-questions !

Yes, ldapsearch with simpleauth works (and should work in samba but 
doesn't, that's the problem).

Just with the code ... see above

Okay.

Okay.

Will try this.

Okay.

Sorry, i'm not a professional programmer,
what does this terminus mean ?

Yes, in openldap-2.2.20/include/ldap.h i found:

typedef struct ldap LDAP;

But where's the struct,
couldn't find the "real" struct ...

Would be fine if you could give me a hint,
where in the sources i can find the complete struct.
In the man-pages for ldap_init i just could find a
minimal version :

typedef struct ldap {
   /* ... other stuff you should not mess with ... */
  char	   ld_lberoptions;
  ....
}

greets Harry


PS.: It's sure a samba problem, but for further investigations i need 
your help, to understand the ldap-portion of the samba-sources ...
