Cloud Connector throws ldapusers cache error after upgrading from 3.9.2 to 5.3.0 and above versions. As a workaround:

  1. Delete the ldapusers cache from the Cloud Connector installed directory (leveldb) and restart the Cloud Connector.
  2. Use the following curl command to push respective properties to YML with the mentioned payload when switching between rocksdb and leveldb:

Switching to leveldb

  "logProcessor":{ "unmatchedtracker.keyValueStoreType":"LEVELDB",
  "ipUserMapperStore.cache.type":"LEVELDB"   },
  "integration": {
    "smtp": {},
    "siem": {},
    "panorama": {},
    "custom_attributes": {},
    "ip_user_mapping": {},
    "syslog": {}

Switching to rocksdb

April 28, 2020 In EC Configuration, when you configure the Custom Attributes Active Directory integration with an AD Server and more than 8 Lakh users, the Evaluate Attributes page takes more than 20 minutes to display the sample set of user attributes. You will only see this issue the first time you configure the AD integration with a fresh MVISION Cloud Connector installation. Once all user details are pulled after this, the page will display much faster.  5.0.1 or 4.3.2 -
April 28, 2020

In MVISION Cloud Connector when a test connection is made to Active Directory, you will see the exception below. This happens because the main thread that is the web request will end once the 10K users reach the iterator, and the result is returned to UI. This triggers a cancellation to the task directoryUserLoaderFuture.

28 Apr 2020 09:14:00 [WARN ] [Active Directory Import Thread] c.s.e.l.i.ActiveDirectoryUsersFetcher| Received Local Error from LDAP Server, will continue

Also, Cloud Connector queries AD for 10,000 users when it goes to the tenant dashboard. This is not the expected behavior. It will be fixed in an upcoming release. 

4.4.1 5.1.0
Mar. 20, 2020 If you install MVISION Cloud Connector 5.0.1 on a tenant that is not yet migrated to McAfee IAM login, you will see an error that says, "Failed to authenticate with remote server, please check username/password/proxy settings." This will be the behavior going forward. If you see this error, contact MVISION Cloud Support. 5.0.1 -
Mar. 18, 2020

Due to a security issue, in the MVISION Cloud Connector Web UI, the password field is removed. If you try to connect Cloud Connector using the Web UI, you may see an error message that reads, "Could not authenticate with Skyhigh cloud services. Please check your Skyhigh credentials." This issue is fixed in 5.0.1. 

5.0.0 5.0.1
Mar. 18, 2020 If you enable RocksDB for dual-mode URL cache in MVISION Cloud, Cloud Connector uses LevelDB only.

4.4.1 5.0.0
Mar. 13, 2020

Cloud Connector was seeing an issue where the SIEM protocol was set as UDP, but it was changed to TCP on its own, so no logs were received. This issue has been fixed. 

4.4.1 5.0.0
Mar. 6, 2020

The API used by MVISION Cloud to pull threat protection incidents had an issue that caused it to send duplicate incidents to SIEM. This has been resolved. If you are seeing duplicate incidents:

  1. Contact MVISION Cloud Support to set a feature flag.
  2. Go to Infrastructure > EC Configuration, and select the SIEM Integration tab. Set the Audit Log Export Type to All Incidents
  3. Contact MVISION Cloud Support again to disable the feature flag.
  4. Set the Audit Log Export Type to New Incidents Only
Feb. 18, 2020

After updating to MVISION Cloud Connector 4.4.x, sometimes the file is not created, which prevents the Syslog service from starting. The Syslog-debug file shows the following exception:

20 Jan 2020 23:54:25 [WARN ] [main] o.s.c.s.ClassPathXmlApplicationContext| 
Exception encountered during context initialization - cancelling refresh 
attempt: org.springframework.beans.factory.BeanInitializationException: 
Could not load properties; nested exception is 
class path resource [] cannot be opened because it 
does not exist

  1. Stop all running services.
  2. Run the Cloud Connector installer to upgrade to the latest version. 
  3. Perform the command shnlpcli jksp --newPass xxxx.
  4. Start Syslog server first and then Cloud Connector.
4.3.2 4.4.0
Dec. 3, 2019 Do not use white space when you create a service group name. You can use "_" or  "-" instead of a space. If there is white space in the service group name, and if the service group is used in Panorama integration, there can be problems accessing the published URL list.  4.3.2 -
Nov. 12, 2019 There is a known issue in MVISION Cloud Connector 4.3.2 where the installation fails with Sanctioned attributes exceptions when the tenant config has more than 10 attributes. This will be fixed in the following release.  4.3.2 4.4.0

4.1.2 -
April 30, 2019

When you upgrade MVISION Cloud Connector from 3.9.x to 4.x.x versions, rule-based configurations with complex rules have failed. 

To workaround this issue, add additional backslashes "\'"to skip the special characters in the additional rule config section. Specifically, configure four slashes for a single slash in the additional config preprocessor rule. For example, to configure this, add the extra backslashes as shown:

  • Configuration: "{"type":"csv","on":",","trim":"true","escape":"\u0000"}" 
  • Configuration with workaround: "{"type":"csv","on":",","trim":"true","escape":"\\\\u0000"}"
4.1.2 -
April 25, 2019

When you upgrade an older version of MVISION Cloud Connector (3.9.x) to the latest version of Cloud Connector (4.x) you may encounter install or upgrade failures that are caused by errors regarding the inability to fetch or install certificates. For details see MVISION Cloud Connector Certificate Issues

March 28, 2019 In the MVISION Cloud Connector web user interface (not the Dashboard interface), the SIEM and PANORAMA configuration tabs are still visible after the upgrade from 4.1.1 to 4.1.2. Make sure to use the Dashboard configuration at Settings > Infrastructure > EC Configuration to configure SIEM and Panorama settings. This will be fixed in a future release.  4.1.2 4.2
March 22, 2019 On Windows VMs, if you switch the Unmatched Key Value Store from LevelDB to RocksDB and see main loop spinning errors or "UnmatchedTracker - Bean instantiation" errors in Cloud Connector debug logs, this may mean that Visual C++ is not installed properly. Install Visual C++ and try again.  4.1.1, 4.1.2 -
Feb 28, 2019 Enterprise Connector is now MVISION Cloud Connector. You'll notice we're transitioning over to our new name in the UI and in all other areas of our product. But the Settings menu still reads Infrastructure > EC Configuration. This is a known issue for this release and will be fixed in a future release.  4.1.1 -
Jan. 30, 2019

For Enterprise Connector 4.1.1, (build 5268) some fonts are missing from the Unix installation. You will see the following error, and then a list of missing fonts.

Nov 29, 2017 Enterprise Connector uses persistent-cache for various tasks. This cache must be periodically rotated to reduce the amount of data held locally by EC, or else it may cause the service to crash. Enhancements have been made to allow cache rotation in #hours instead of #days, as the amount of data could be in GBs. And a new property, leveldb.dualmode.maxhours, has been added to rotate older entries against dual-mode processing. 3.6 3.7
Sept 12, 2017 If Excel spreadsheet tabs include tokenized text that is less than 31 characters, the text for the tab cannot be detokenized. This is a limitation of Excel. This issue will be fixed in the 3.6.1 release.  3.6 3.6.1

March 31, 2017 When Enterprise Connector is reinstalled, you can reuse the existing DNS. But during installation, if you do not reuse, it creates a new DNS record for EC, which can cause confusion. Contact MVISION Cloud Support to request that they delete old and invalid EC DNS records. Existing behavoir  
March 28, 2017 Explicit de-tokenization of data from .csv files on EC WebUI fails if the file had less than 5 rows. 3.3 3.3 SP1
March 28, 2017 If AD attributes are configured to be tokenized (through the propertycustom_attributes.tokenize=true via log file), then logback.xml file also needs to be edited as below: 

After this line:
<logger name="org.springframework" level="WARN" additivity="true"/>

add the following line:
<logger name="" level="INFO" additivity="true"/>

3.3 3.3 SP1
March 28, 2017 The feature Receiving Notification Emails from Your Corporate Domain in the 3.3 release did not have an explicit property to specify the sender. This is fixed. You may configure the property mail.smtp.sender in the file. 3.3 3.3 SP1
