Hi all!

```bash [root@kamailio kamailio]# cat /etc/rocky-release Rocky Linux release 9.5 (Blue Onyx) [root@kamailio kamailio]# sestatus SELinux status: disabled [root@kamailio kamailio]# kamailio -v version: kamailio 6.0.1 (x86_64/linux) fce50d flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_SEND_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: fce50d compiled on 00:00:00 Sep 13 2022 with gcc 11.5.0 ```

I am trying to use the mysql option group name `kamailio` to connect to MySQL:

``` #!ifdef WITH_MYSQL #!trydef DBURL "mysql://[kamailio]/kamailio" #!endif ```

My /etc/my.cnf file: ``` # # This group is read both both by the client and the server # use it for options that affect everything # [client-server]

# # include all files from the config directory # !includedir /etc/my.cnf.d/

```

/etc/my.cnf.d/kamailio.cnf: ``` [kamailio] socket=/var/lib/mysql/mysql.sock user = kamailio password = ... default-character-set = utf8 ```

Let's check the group name and permissions (for test purposes):

```bash [root@kamailio kamailio]# usermod -s /bin/sh kamailio [root@kamailio kamailio]# su - kamailio -c 'my_print_defaults -c /etc/my.cnf kamailio' --socket=/var/lib/mysql/mysql.sock --user=kamailio --password=... --default-character-set=utf8 ```

The cuts from log file:

Strange things happens if I place [kamailio] configuration into /etc/my.cnf - everything works like a charm! What could be wrong? How to check by other means? The problem is exactly that kamailio can't read the configuration in the external file /etc/my.cnf.d/kamailio.cnf
