Olá pessoal!
Estou configurando um TS no active directory para acesso de terminais windows a ele. Tenho uma maquina com Linux Mint versão 21 com a parte grafica cinnamon e quero colocar essa maquina para ser um terminal server para que cliente que estejam no domínio do active directory(com as devidas permissões) a acesse. Ela já esta inclusa no domínio, no qual a inserir pelo aplicativo CID, instalei o XRDP e com isso consigo acessar remoto.

O meu impasse é o seguinte, quando incluo um usuário que foi cadastrado no AD com o primeiro nome, consigo acessar normalmente, mas quando uso um usuário que tenha se cadastro com ponto, exemplo: miguel.silva, ele não acessar. Alguém poderia dar-me um dica para possível resolução de problema?

Eu tenho a seguinte estrutura:

Eu tenho um activi deretory com algum usuários e tenho um serviço TS em outro computador, também com windows server, onde esses usuário fazem acesso para trabalhar em um sistema de forma remota. Desta forma, estou querendo trocar esse TS windows server, por um linux. A minha dificuldade esta em fazer o acesso a esse linux, quer será o meu serviço de TS, com os usuário do AD, pois quando coloco um usuário, do AD, com nome composto ele não loga o computador, mas quando coloco um usuário sem nome composto, ele passa. Você consegui entender, mais ou menos, o cenário?

Agora entendi sim.
Tem que ver nos logs do Server linux, se gera algum erro na hora do login com nome composto, pq nativamente não deveria ser um problema.

Carlos, fiz algums procedimento, mas nada, não consigo agora logar com nehum usuário do meu AD. Caso possa me dar um orientação, segue o logo e em anexo algums comando que usei para verificar a comunicação do meu computador com o domínio.

Vc havia dito que não conseguiu logar com usuário com nomes compostas como "xxxx.yyyy", mas usuário apenas "xxxx" conseguia, não entendi agora.
Não funciona nenhum então ?

Estava, quando fiz a instalação do CID conseguia logar com usuário sem nomes composto. Mas, depois que retirei do domínio e recoloquei, não consigo acessar com mais nenhum usuário.

Consegui, para deixar registado o que fiz para conseguir adicionar o Linux mint 21 Vanessa Cinnamon no Active Dairetory do Windows Server 2012 R2:

1 - Primeiro instalei o CID:

Ubuntu
$ sudo add-apt-repository ppa:emoraes25/cid
$ sudo apt update
$ sudo apt install cid cid-gtk

2- Depois editei os arquivos “/etc/hosts”, "/etc/resolv.conf" e "krb5.conf".

-No “/etc/hosts” coloquei as seguintes informações:

127.0.0.1 nome-do-host.domínio.local localhost nome-do-host.domínio
192.168.0.2(IP do controlador de domínio) nome-do-controlador-de-domínio

-No "/etc/resolv.conf" coloquei as seguintes informações.

search controlador-domínio
domain controlador-domínio
nameserver IP-controlador-dominio-1°
nameserver IP-controlador-dominio-2°

-Por fim, no "krb5.conf":

[libdefaults]
default_realm = SEUDOMINIO(COM LETRAS MAIÚSCULAS)
[realms]
SEUDOMINIO = {
kdc = seudominio
default_domain = SEUDOMINIO
admin_server = seudominio
kpasswd_server = nome-controlador- seudominio
}
[domain_realm]
. seudominio = SEUDOMINIO
