ReconnectLDAPObject doesn't reconnect after main failure

[Alain Spineux]

Yes, we did it !

My test case is working with your CVS !
I put it at the end.

And what about the idea to put the

try:
except ldap.SERVER_DOWN,e:
   SimpleLDAPObject.unbind_s(self)

in the function _ldap_call too ?
This will correct also SimpleLDAPObject ?


import sys, os, time
import ldap, ldapurl

host='localhost'
port=389
who='cn=nobody,cn=internal,dc=asxnet,dc=loc'
cred='iMmTWz5pJ+lwY7i6M/BU61ngo1aBLyqQhRrrKbEc'
dn='dc=asxnet,dc=loc'

def ldap_service(action):
    os.system('/kolab/bin/openpkg rc openldap %s' % action)
    if action.endswith('start'):
        time.sleep(1)

def check_connection():
    whoami=l.whoami_s()
    print 'whoami', whoami
    # this search dont give any result as anonymous, but well if
loggged as nobody
    #result=l.search_s(ldap_url.dn, ldap.SCOPE_SUBTREE,
"(member=cn=domain.maintainer
mydomain.loc,cn=internal,dc=asxnet,dc=loc)")
    #print 'search', result

ldap_url=ldapurl.LDAPUrl('ldap://%s:%d/%s' % (host, port, dn))
ldap_url.applyDefaults({
    'who': who,
    'cred' : cred, })

# to be sure the server is up
ldap_service('stop')
ldap_service('start')

l=ldap.ldapobject.ReconnectLDAPObject(ldap_url.initializeUrl(),1) # I
dont use ReconnectLDAPObject !
l.simple_bind_s(ldap_url.who, ldap_url.cred)
check_connection()

print 'Wait 120s'
time.sleep(120)
check_connection()

print 'restart service'
ldap_service('stop')
ldap_service('start')
check_connection()

print 'stop service'
ldap_service('stop')
try:
    check_connection()
except ldap.SERVER_DOWN:
    print 'check failed, OK'

print 'restart service'
ldap_service('start')
check_connection()
