Python LDAP module version problem

[CyberNerd]

Ages ago I wrote a python program on v2.3 - it works fine. I was re-writing the original program to do something else and I noticed it failed using a newer version of python/python-ldap.

I'm not sure why, but would rather update the program than downgrade python module. Any pointers please. :?

 

this works:

python-ldap.i386 0:2.0.1-2

 

python
Python 2.3.4 (#1, Oct 11 2006, 06:18:43)
[GCC 3.4.6 20060404 (Red Hat 3.4.6-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import ldap
>>> domain = "example.com"
>>> l=ldap.initialize("ldap://server."+domain+":389")
>>> l.simple_bind_s("domain\\username","password")
>>>

 

this fails:

Python-ldap version: 2.0.4-1ubuntu4

 

Python 2.4.3 (#2, Oct  6 2006, 07:49:22)
[GCC 4.0.3 (Ubuntu 4.0.3-1ubuntu5)] on linux2

The ldap.initalise function doesn't exist anymore in the python-ldap module in ubuntu. The function has been renamed to ldap.open().

[CyberNerd]

thanks, but I'm gettign the other errors with ldap.open().

I've got something half working, but how much do these things change in python? is there any way of achieving backwards comatibility other than keeping another install of older versons?

[Geoff]

No, go read the api documentation for ldap-python and fix your script.

[CyberNerd]

now I'm really confused.

"current" documentation is 2004 for v2.03 and states:

The following example demonstrates how to open an LDAP server using the ldap module.

 

>>> import ldap

>>> l = ldap.initialize("ldap://my-ldap-server.my-domain:389")

>>> l.simple_bind_s("","")

>>> l.search_s("o=My Organisation, c=AU", ldap.SCOPE_SUBTREE, "objectclass=*")

 

The example (no docs I could find) in the latest python-ldap v2.2.1 also uses ldap.initialize:

 

# Create LDAPObject instance

l = ldap.initialize('ldaps://localhost:1636',trace_level=ldapmodule_trace_level,trace_file=ldapmodule_trace_file)

# Set LDAP protocol version used

l.protocol_version=ldap.VERSION3

# Try a bind to provoke failure if protocol version is not supported

l.bind_s('','',ldap.AUTH_SIMPLE)

# Close connection

l.unbind_s()

 

So is this ldap.initialize problem specific to Ubuntu's implementation?

[CyberNerd]

I just tried the original script on Zenwalk with python 2.4 and python-ldap 2.2.1 and it worked fine.

I think this must be a problem with (my) ubuntu 6,06amd64. or the 2.04 version of python-ldap.
