MariadB的GSSAPI身份验证似乎有效。我使用身份验证方法= GSSAPI创建了PhpMyAdmin的用户。在CLI中，我可以连接，请参阅下图：
succcessful mysql与域用户连接试图与连接时
if (($dbcon=mysqli_connect("localhost","$mysql_userid","$password"))===FALSE) {
exit("4:Login process failed while connecting to database");
echo "Debug-Fehlermeldung: " . mysqli_connect_error . PHP_EOL;
}else{
$auth_result=TRUE;
}
Warning: mysqli_connect(): The server requested authentication method unknown to the client [auth_gssapi_client] in C:\xampp\htdocs\oa5-maria\trunk\login.php on line 82
Warning: mysqli_connect(): (HY000/2054): The server requested authentication method unknown to the client in C:\xampp\htdocs\oa5-maria\trunk\login.php on line 82

I已在my.ini文件中设置默认授权 - plugin = gssapi。但是我不知道这是否是正确的方法。 您有什么建议可以解决这个问题？
这是我的我的文件：
# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# You can copy this file to
# C:/xampp/mysql/bin/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is C:/xampp/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>

客户和PHP之间的区别是，客户端与libmariaDB链接（因此，可以加载auth_gssapi_plugin，而mysqli则可以针对libmysql或PHP的内部mysqlnd驱动程序链接。
BesideKerberos/gssapi Mariadb还提供ED25519和PAM身份验证（通过Dialog插件），Libmysql和MySQLND不支持。构建ext/mysqli与Mariadb连接器/C不幸的是无效，最近拒绝了该问题的最新拉动请求。
i遇到了在
Windows10上运行的相同错误，并使用
php8.2.1和mariadb11.4.4
当然，您必须设置数据库值才能表示真实的数据库。
// Set the parameters for mysqli_connect().
$Host = 'localhost';
$User = 'my_database_user';
$Pass = 'my_database_password';
$Name = 'my_database_name';
$Port = null;
$Socket = null;
// Make some checks...
// This will be the cause of the error.
if (empty($pass)) $Pass = NULL;
// Connect to the database.
// The error will be generated due to a NULL parameter.
$DB = mysqli_connect($Host, $User, $Pass, $Name, $Port, $Socket);
if (mysqli_connect_errno() != 0)
die('mysqli_connect() error');
else
echo("<p>Connected...</p>");
// Close the Connection.
mysqli_close($DB);
我的示例：
在调用mysqli_connect（）之前，我们对参数进行了一些检查，例如：
在此示例中，$ Pass是拼写错误的，因此它是不确定的，empty（）返回true和$pass将设置为null
； 如果您致电Mysqli_connect（$ host，$ user，$ pass，$ name，$ port，$ socket），则$ pass为nulsnull
，并返回我们在此处讨论的错误。您可以说这是一个愚蠢的错误，但这通常就是这样。解释：
当mysqli_connect（）接收到null作为密码时，PHP获取在mysqli.default_pw上保存的密码。如果未设置此值，MySQLI_Connect（）将返回上述错误。该原则适用于所有mysqli_connect（）参数，并且在php.ini文件中适用于它们：
mysqli.default_port，mysqli.default_socket，mysqli.default_host，mysqli.defeault_user。如果您没有明确将参数设置为null，则总会有一个不存在的值或无效的值等。 。如php.ini中所述，这是一个非常糟糕的主意。任何PHP用户都可以使用这样的命令显示密码：
echo get_cfg_var("mysqli.default_pw");
结论： 最好要做的就是仔细检查和三倍检查所有mysqli_connect（）参数的值，以查看它们是否有问题。
