ValueError: too many values to unpack (expected 2)

when i try to get the groups from within a plone5.2 instance.

The ldap directory is a meta ldap

the ldap tree may be complex

ROOT TREE = dc=aaa,dc=fr

META is so that
the groups will be located in
cn=group_cn0,ou=Group,dc=XX,dc=aaa,dc=fr
cn=group_cn1,ou=Group,dc=YY,dc=aaa,dc=fr

Hi,

can you please add a breakpoint here https://github.com/conestack/node.ext.ldap/blob/master/src/node/ext/ldap/_node.py#L573 and have a look what search_func actually is and what it returns?

[gnafou]

Hello,

search_func is '<bound method debug..wrapped of <dc=em-ldap,dc=fr - False>>'
search_func(kw) leads to the error "* ValueError: too many values to unpack (expected 2)"
kw is "{'attrlist': ['rdn', 'cn'], 'page_size': 30, 'cookie': None}"

[rnixx]

Have you called search_func(**kw) in debugger? Does the error happen in the search function or is the return value wrong? Can you please step into search function if the error happens there?
