Hi All. I have: - one devel application server with php53-mysql-5.3.27-1 MariaDB-compat-5.5.32-1.x86_64 MariaDB-common-5.5.32-1.x86_64 MariaDB-shared-5.5.32-1.x86_64 MariaDB-client-5.5.32-1.x86_64 - one devel database server with MariaDB-compat-5.5.30-1.x86_64 MariaDB-server-5.5.30-1.x86_64 MariaDB-common-5.5.30-1.x86_64 MariaDB-shared-5.5.30-1.x86_64 MariaDB-client-5.5.30-1.x86_64 When I try to make a connection from devel to database server with php mysql_connect function then when I am using: - user with local authentication: connection is ok; - user with pam/ldap authentication I get error "Client does not support authentication protocol requested by server; consider upgrading MariaDB client error 1251" When I use mysql command on application server I can connect to the database server with both users, so only php does not work. Have you got similar issues? Any clues anout how to solve the problem? Best regards, Rafal Radecki.
