LDIF Generation using Python-LDAP

[Guruprasad <lgp...@gm...>]

Hi,
I tried generating a LDIF file from a dictionary using 'ldif' module
as illustrated in http://www.python-ldap.org/doc/html/ldif.html. But
at the end of the LDIF data, I get a newline and a 'None', whereas
there is no such thing in the result shown in that example. How to get
rid of those unwanted characters. I am using Python-LDAP 2.3.5-1 on
Debian Lenny.

Thank you.

Regards,
Guruprasad.

Could you please post your code (in a short form) demonstrating the
issue? Note that there is a new-line after each entry record. But was
'None' is in your case is not clear to me.

Ciao, Michael.

Basically what I am trying to do with this code is that, I manipulate
the result returned by ldapsearch to remove some attributes and
generate a LDIF output for the modified entry.

<code>
        res_type, result_data=l.result(res_id,0)
        if (result_data==[]):
            break
        dn=result_data[0][0]
	resd=result_data[0][1]
        resd["objectClass"].remove("inetLocalMailRecipient")
	    resd["objectClass"].remove("organizationalPerson")
	    resd["objectClass"].remove("inetOrgPerson")
        resd["objectClass"].remove("posixAccount")
        lw=ldif.LDIFWriter(sys.stdout)
	guru=lw.unparse(dn,resd)
	print guru
</code>

Is it some issue or am I making some mistakes with general usage of Python?

Thank you.

My ldapsearch query returns only one record. I have written such a filter.

Sorry, my crystal ball is a bit blurry. I can't help without really
knowing what you're trying to achieve.

Ciao, Michael.

Your code looks like processing of LDAP search results (because of the
res_type). I'd recommend to look at the actual data in dictionary resd.
Also note that the identiation seems wrong. This could be because of
cut&paste to your MUA from the editor with different tab-interpretation.
But make sure identiation is correct in the real code.

Ciao, Michael.

The indentation is correct in the real code. The dictionary 'resd' has
the values returned by the ldapsearch and there is no 'None' anywhere
in it.


Thank you.

I think your interpretation of the output is wrong. Method
LDIFWrite.unparse() outputs the LDIF to the file object (in your case
sys.stdout). If you print the result of method unparse() that's
obviously None.

Ciao, Michael.
