How to fix water error in Gosa 2.6?

Question

linux

There is a server on Ubuntu 10.04.03, it has samba 3.4.7 + OpenLdap 2.4.21 + gosa2.6
Gosa manages ldap accounts and samba resources
One fine morning, when trying to enter the Gosa admin panel, I got this error.
=====
Fatal error
FATAL: Error when connecting the LDAP. Server said 'Could not bind to cn=admin,dc=local,dc=inc ((unknown error code), while operating on '' using LDAP server 'ldap://localhost:389')'.
Please fix the above error and reload the page.
====
I checked all the settings in the configs - everything is spelled out correctly and the logins and passwords of the admin.
Such an error occurs when any user tries, and even without a user, just with the sign in button.

Answer 1

it says in black and white - I can't connect to ldap... is the ldap server running?
