Debian 9 + MariaDB = unable to start Kopano server

Hi all,
I’ve a problem with my new fresh installation of Kopano server.
System: Debian 9.1 x64
Kopano version:

I’ve install SLAPD, Apache and php7 and some other dependencies.
I’ve install all *.deb packages.
I’ve change login autenthication type in LDAP, add the password of root user for MySQL ecc.
When I try to start kopano-server I receive this error:

Fri Dec 1 17:56:33 2017: [ notice] Starting kopano-server version (pid 19891)
Fri Dec 1 17:56:33 2017: [error ] KDatabase::Connect(): database access error Unknown error code (0x80000007), mysql error: Access denied for user ‘root’@‘localhost’
Fri Dec 1 17:56:33 2017: [crit ] Unable to connect to database: MYSQL not initialized
Fri Dec 1 17:56:33 2017: [ notice] Server shutdown complete.

I’ve try to add kopano user to mysql group.

Now kopano-server doesn’t start but I don’t receive any error in server.log.

If I list databases:

MariaDB [(none)]> show databases;
| Database |
| information_schema |
| kopano |
| mysql |
| performance_schema |
4 rows in set (0.01 sec)

Can anyone confirm same problem?


Hi Mk,

The root user in mariadb is only accessible if you are logged in as root as it is using the unix_socket authentication.
Kopano-core is running under the kopano user and therefore you can’t use the root user.


Kind regards,
