Mariadb 11.4.2 on Windows 11 - mariabackup error: Authentication plugin 'auth_gssapi_client' cannot be loaded
On a freshly installed MariaDB v 11.4.2 I was trying to do a full backup using the command: mariabackup --backup --target-dir=e:\mdbbackup\28072024 -u=root -p='.....' The error I got was: Authentication plugin 'auth_gssapi_client' cannot be loaded: The specified module could not be found.
I checked and found the auth_gssapi_client.dll at: ...\mariadb\lib\plugin. I browsed for possible solutions but all that I saw were intended for older MariaDB versions, so ... I also tried to put the following in my.ini and restarted the mysql: [mysqld] plugin_load_add = auth_gssapi_client ... but the error persisted. Now I don't know how to proceed

This plugin_load_add is out of place. You can't load client plugin into server.
You just need plugin-dir under [client], usually. But mariabackup is slightly (or not so slightly) weird, it uses the server's builtin client, so there can be problems.
An educated guess is that you simply mistype the password, therefore server tries to use another plugin, which is gssapi, which then fails on reasons we do not know of yet.
Can also share you my.ini? Best thing you can do is to create a bug at https://jira.mariadb.org/ , with detailed "how to reproduce". I gave it a try, and it worked for me, but maybe you installed it differently somehow.
