Changing default password for 'admin' and 'kibanaserver' - documentation refers to incorrect folder.

[ativey-ops]

Following the official documentation carefully, password changes fail due to the "config" directory being referred to when it appears to no longer exist.

Using the documented variable assignments below:

export INSTALLATION_DIR=/usr/share/wazuh-indexer
export CONFIG_DIR=$INSTALLATION_DIR/config
CACERT=$CONFIG_DIR/certs/root-ca.pem
KEY=$CONFIG_DIR/certs/admin-key.pem
CERT=$CONFIG_DIR/certs/admin.pem
export JAVA_HOME=/usr/share/wazuh-indexer/jdk

Results in the following error:

Security Admin v7
Will connect to localhost:9200 ... done
ERR: An unexpected IllegalArgumentException occured: Could not find certificate file /usr/share/wazuh-indexer/config/certs/root-ca.pem

On a fresh setup of Wazuh, the folder "config" does not exist at /user/share/wazuh-indexer within the container. Running with the following set of commands, however, results in successful password changes:

export INSTALLATION_DIR=/usr/share/wazuh-indexer
export CONFIG_DIR=$INSTALLATION_DIR
CACERT=$CONFIG_DIR/certs/root-ca.pem
KEY=$CONFIG_DIR/certs/admin-key.pem
CERT=$CONFIG_DIR/certs/admin.pem
export JAVA_HOME=/usr/share/wazuh-indexer/jdk

Since I am not familiar with the securityadmin.sh script itself, I just adjusted the assignment of CONFIG_DIR rather than removing it entirely.
