[Zope] Strange error/traceback

[Phil Harris]

Chris/all,

as requested by ChrisW

def auth_LDAP(self,cn=None,pwd=None):
    if cn==None or pwd==None:
            return None
    l=ldap.open('medico.uwcm.ac.uk')
    cn='cn='+cn
    l.search_s('',ldap.SCOPE_SUBTREE,cn) # this is where it fails
    res=l.result()
    auth=[res[1][0][0],pwd]
    l.simple_bind_s(auth[0],auth[1])
    l.unbind_s()
    return 1

It's basically trying to :

1.    do an anonymous bind to an LDAP server to find the dn of a particular
user
2.    take the dn returned and then try to authenticate that user

but it don't get that far.

(I know there is no error trapping etc. I took it out to see what exactly
was happening.)

It always fails on the l.search_s, the cn and the pwd are returned from a
form (actually the login form of LoginManager).

I know the function works when not called from Zope but I really can't see
how that could possibly matter.

Any ideas?

Phil
