ldap.DECODING_ERROR in ldap.dn.str2dn with python2.4 on amd64

[Arvid R. <re...@un...>]

Hello,

we had a problem with ldap.dn.str2dn showing instable behavior and throwing 
ldap.DECODING_ERROR in python2.4 Debian Lenny (amd64).
It seems that using PyArg_ParseTuple with format string "z#" and saving the 
length of the string directly into the berval member bv_len does not store a 
correct value, which in turn causes the problem in ldap_bv2dn. It seems that 
str2dn is the only location in python-ldap (2.3.5) where this technique is 
used, and the problems seems to affect only amd64 and might be caused by a 
leak in the PyArg_ParseTuple routine of python2.4.

The attached patch solved the problem for us.

Cheers,
Arvid
