The solution to the error “ImportError: No module named ldap”

Installed iRedMail on Ubuntu Server in February 2016 and noticed an error when trying to send a message via Roundcube:

SMTP error (451): Unable to add recipient “Email” (4.3.5 Server configuration problem)

I checked if iredapd is running:

telnet localhost 7777

It turned out that it was not running because the response from telnet was displayed:

Unable to connect to remote host: Connection refused

Tried to run:

sudo /etc/init.d/iredapd start

To which he received the answer:

ImportError: No module named ldap

I installed the module with the command:

sudo apt-get install python-ldap

Execute the commands:

sudo -i
cd /opt/iredapd/
find . -name '*pyc' | xargs rm -f {}

Now restart the service:

sudo service iredapd restart

Done, there is no error.

Why the Far Cry 4 progress not saving?

I noticed once on one computer that the game Far Cry 4 can not save the game.

Far Cry 4 itself was not installed, but was moved from another computer to the folder + transferred to Save to Documents.

The reason for not saving was probably different owners to the files and directory of the game, this quickest solution is right-clicking on the game’s shortcut, then “Properties” – tab “Compatibility” and setting the checkbox “Run this program as administrator“, click “ОК“.

Done, there should not be any problems with saving.
