Hi community,

I've installed mailman (Version 2.1.12) at my CentOS 6 server and in gernerally it works fine.

So know I want to use the LDAP Extension (https://bugs.launchpad.net/mailman/+bug/558106) to build my mailingliste in LDAP.
After some problems with Python-ldap now i configured a mailinglist "test" and created a extend.py file in the Listfolder, like this:

from Mailman.LDAPMemberships import LDAPMemberships

def extend(list):
    ldap = LDAPMemberships(list)
    ldap.ldapdigestsearch = None        # if digests are enabled, this search is for digest members.    
    ldap.ldapserver = "ldap://ldap.<myserver>.de:389" # your LDAP server
    ldap.ldapbasedn = "cn=test,ou=mailman,ou=Mandanten,dc=<my-domain>,dc=de" # your base DN
    ldap.ldapbinddn = ''                 # bind DN that can access 'mail' field
    ldap.ldappasswd = ''                 # bind password for ldapbinddn
    ldap.ldaptls = False            # Use TLS, must be set to True or False
    ldap.ldapmemberattr = 'member'
    ldap.ldapgroupattr = '' # if using groups, attribute that holds DN info.
                            # Omit or set to null string if not using groups.
    list._memberadaptor = ldap 

The LDAP entry "cn=test,…" contains some "members".

Now I want to see the members in the admin web frontend. By choosing the menu option "Membership Management" I get an error message in my webbrowser (Bug in Mailman).
In the error logfile I found this:

admin(24882): [----- Traceback ------] 
admin(24882): Traceback (most recent call last):

admin(24882): sys.path        =   /usr 
admin(24882): sys.platform    =   linux2 

The important line is this: admin(24882): AttributeError: LDAPMemberships instance has no attribute '_LDAPMemberships__ldap_get_regularmembers'

But I don't know what it means … it seems that another Funktion doesn't work correctly?!
Any ideas?

Best regards,
