libpam-ldapd não está procurando grupos secundários

Question

Estou migrando de libpam-ldap para libpam-ldapd . Estou tendo algum problema para reunir os grupos secundários do LDAP.

Em libpam-ldap , eu tive isso no arquivo /etc/ldap.conf :

nss_schema rfc2307bis
nss_base_passwd         ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es
nss_base_shadow         ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es
nss_base_group          ou=Groups,ou=CITIUS,dc=inv,dc=usc,dc=es
nss_map_attribute       uniqueMember  member

O mapeamento está lá porque estou usando groupOfNames em vez de groupOfUniqueNames classe LDAP para grupos, portanto, o atributo que nomeia os membros é denominado member em vez de uniqueMember .

Agora, quero fazer o mesmo usando libpam-ldapd , mas não consigo fazer isso funcionar. Aqui está a parte relevante do meu /etc/nslcd.conf :

base passwd         ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es
base shadow         ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es
base group          ou=Groups,ou=CITIUS,dc=inv,dc=usc,dc=es
map group uniqueMember member

E esta é a saída de depuração do nslcd, quando um usuário é autenticado:

Parece-me que nem sequer tentará procurar grupos. O que estou fazendo errado? Não vejo nada relevante para as informações sobre meus problemas nos documentos . Provavelmente não estou entendendo como a opção map funciona.

    

Answer 1

Acredito que o parâmetro map group precisa ser associado a um parâmetro filter group correspondente. Aqui está como eu o uso conectando ao Active Directory:

filter passwd (&(objectClass=user)(memberOf:1.2.840.113556.1.4.1941:=CN=Linux-SA,OU=Groups,DC=global,DC=example,DC=com)(!(objectClass=computer))(uidNumber=*)(unixHomeDirectory=*)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))
map    passwd uid              sAMAccountName
map    passwd homeDirectory    unixHomeDirectory
map    passwd gecos            displayName
map    passwd loginShell       "/bin/bash"
filter shadow (&(objectClass=user)(!(objectClass=computer))(uidNumber=*)(unixHomeDirectory=*))
map    shadow uid              sAMAccountName
map    shadow shadowLastChange pwdLastSet
filter group  (&(objectClass=group)(gidNumber=*))
map    group  uniqueMember        member
