Consistency check

[Cognos8]

1)

We are migrating from Cognos 8.2 to Cognos 8.4 .Once everything is moved for personal insurance LOB (ex: 100 out of total 500 user), This 100 user permission has denied from AD group , so they have access to c84 not c82. The problem here is they had scheduled 1000 of reports in my folder every day, so now this reports are getting failed due to access issue. Unfortunately we don't have audit package in c82. So I want to find users who have been removed from AD group and scheduled reports in c82 and this needs to be disabled.

2) If I am able to find the list of groups whose access has been denied, then how can I disable their scheduled job at a stretch in cognos 8.2?

I gave try with new consistency check but got the below error.

CM-ADM-4004 An error occurred while retrieving external security objects from the namespace 'PROD_LDAP' named 'PROD_LDAP'. A consistency check was not performed on this namespace. MSG_NOT_FOUND=AAA Exception occurred in consistencyCheck CAM-AAA-0045 The call to the LDAP function 'doLDAPSearch_s/LdapAPIWrapper_ldap_search_ext_s' returned with the error code: '4'.
