Gosa com o openldap dando erro de php na inicialização

Question

Estou tentando configurar o GOsa e o OpenLDAP em uma máquina Centos 7 e estou encontrando alguns problemas.

Principalmente quando eu acesso a página da Web / gosa, recebo o seguinte erro:

Fatal error: Class 'session' not found in /usr/share/gosa/include/php_setup.inc on line 91

Etapas de instalação:

• Adição do link repositório yum
• Instalação dos módulos yum (versão mais recente):
  • openldap
  • openldap-clients
  • openldap-servers
  • gosa-schema.noarch
  • gosa-plugin-systems.noarch
  • gosa-plugin-sudo.noarch
  • gosa-plugin-squid.noarch
  • gosa-plugin-samba.noarch
  • gosa-plugin-rolemanagement.noarch
  • gosa-plugin-pureftpd.noarch
  • gosa-plugin-mail.noarch
  • gosa-plugin-log.noarch
  • gosa-plugin-ldapmanager.noarch
  • gosa-plugin-dns.noarch
  • gosa-plugin-dhcp.noarch
  • gosa-plugin-connectivity.noarch
  • gosa-plugin-addressbook.noarch
  • gosa.noarch
• mudando expose_php off e magic_quotes_gpc em arquivos php
• Configurando o /etc/openldap/ldap.conf da seguinte maneira (mais tarde)
• copiando /usr/share/gosa/plugins/pureftpd/contrib/pureftpd.schema para /etc/openldap/schema/gosa/pureftpd.schema
• copiando /usr/share/gosa/plugins/dns/contrib/dnszone.schema para /etc/openldap/schema/gosa/dnszone.schema
• adicionando gosa_custom.schema a /etc/openldap/schema/gosa_custom.schema (segue mais adiante)
• abrindo o acesso do apache definindo Exija tudo concedido no diretório /
• copiando /usr/share/openldap-servers/DB_CONFIG.example para / var / lib / ldap / DB_CONFIG
• executando / usr / sbin / update-gosa
