Eu uso um sistema de helpdesk em nossa intranet que configurei para login único via LDAP/Active Directory.
O próprio servidor de helpdesk reside em uma caixa do servidor Ubuntu 16.04 rodando em Apache, versão do servidor: Apache/2.4.18 (Ubuntu) Servidor construído: 2018-04-18T14:53:04
Possui dois portais, um para os Agentes fazerem login e outro para os Clientes/Usuários Finais fazerem login e verificarem os tickets que colocaram.
Eu tenho o cliente funcionando, ele faz login automaticamente e funciona perfeitamente.
No entanto, o Portal do Agente ainda está enfrentando problemas. O LDAP/AD funciona bem, porque os agentes ainda podem autenticar usando suas credenciais do Active Directory; no entanto, ele não os registra perfeitamente via SSO como deveria.
Estou recebendo os erros atuais no meu log do Apache e não tenho certeza do que eles estão tentando me dizer.
