我已经在使用 Realm 连接到 Microsoft AD 森林的 linux 机器上配置了 SSSD。
我的最终目标是使用存储在 Microsoft AD 中的 SSH 密钥登录 CentOS 机器
以下是设置详细信息：
- 适用于 Microsoft AD 的 EC2 Windows
- 配置了 SSSD 的 EC2 Amazon Linux
我可以使用 AD 用户名和密码登录 linux 机器。
我现在已将 SSH 公钥存储在 Microsoft AD altSecurityIdentities用户属性以及sshPublicKeys属性中。
以下是 SSSD 的配置文件
[sssd]
domains = test.com
config_file_version = 2
services = nss, pam, ssh, sudo
debug_level=10
[domain/test.com]
ad_domain = test.com
ad_server = test.com
krb5_realm = TEST.COM
realmd_tags = manages-system joined-with-samba
cache_credentials = True
id_provider = ad
krb5_store_password_if_offline = True
default_shell = /bin/bash
ldap_id_mapping = True
use_fully_qualified_names = False
fallback_homedir = /home/%u
access_provider = ad
#SSH KEY FETCH
ldap_user_extra_attrs = altSecurityIdentities:altSecurityIdentities
ldap_user_ssh_public_key = altSecurityIdentities

当我尝试使用以下命令使用 ssh 登录时
ssh demo_user@test.com@<IP>
我收到以下错误
demo_user@test.com@<IP>: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
我已经尝试过以下事情
挖
id demo_user@test.com
uid=1277801117(demo_user) gid=1277800513(域用户) groups=1277800513(域用户)
我已经尝试重新启动 SSSD 恶魔，但它并没有像几个论坛中所建议的那样有帮助
有什么办法可以使这项工作
