In this scenario, the sssd behavior is not consistent and depends on the ldap_deref_threshold parameter, that controls if an attribute scoped query (ASQ) will be used or if the group members will be searched individually. If an ASQ operation is issued, the operation will fail because the referenced entry can't be parsed and this can lead to missing groups and makes impossible to use the group in simple access provider. On the other hand, when the group members are looked up individually sssd just ignores the unreadable entry. This patch adds a new parameter 'ldap_ignore_unreadable_references' to control if the current operation will fail when an unreadable entry is found or the entry will be ignored, regardless if sssd issued an ASQ or the members are looked up individually. The issue can be replicated deploying this AD setup: CN=users,DC=aforest,DC=ad CN=g1,CN=users,DC=aforest,DC=ad member: CN=g2,CN=users,DC=aforest,DC=ad member: CN=g3,CN=users,DC=aforest,DC=ad member: CN=g4,CN=users,DC=aforest,DC=ad member: CN=g5,CN=users,DC=aforest,DC=ad member: CN=user1,CN=users,DC=aforest,DC=ad CN=g2,CN=users,DC=aforest,DC=ad member: CN=g3,CN=users,DC=aforest,DC=ad member: CN=g4,CN=users,DC=aforest,DC=ad member: CN=g5,CN=users,DC=aforest,DC=ad member: CN=user2,CN=users,DC=aforest,DC=ad memberOf: CN=g1,CN=users,DC=aforest,DC=ad CN=g3,CN=users,DC=aforest,DC=ad <-- Deny access to sssd account member: CN=g4,CN=users,DC=aforest,DC=ad member: CN=g5,CN=users,DC=aforest,DC=ad member: CN=user3,CN=users,DC=aforest,DC=ad memberOf: CN=g2,CN=users,DC=aforest,DC=ad memberOf: CN=g1,CN=users,DC=aforest,DC=ad CN=g4,CN=users,DC=aforest,DC=ad member: CN=g5,CN=users,DC=aforest,DC=ad member: CN=user5,CN=users,DC=aforest,DC=ad memberOf: CN=g3,CN=users,DC=aforest,DC=ad memberOf: CN=g2,CN=users,DC=aforest,DC=ad memberOf: CN=g1,CN=users,DC=aforest,DC=ad CN=g5,CN=users,DC=aforest,DC=ad member: CN=user5,CN=users,DC=aforest,DC=ad memberOf: CN=g4,CN=users,DC=aforest,DC=ad memberOf: CN=g3,CN=users,DC=aforest,DC=ad memberOf: CN=g2,CN=users,DC=aforest,DC=ad memberOf: CN=g1,CN=users,DC=aforest,DC=ad CN=user1,CN=users,DC=aforest,DC=ad memberOf: CN=g1,CN=users,DC=aforest,DC=ad CN=user2,CN=users,DC=aforest,DC=ad memberOf: CN=g2,CN=users,DC=aforest,DC=ad CN=user3,CN=users,DC=aforest,DC=ad memberOf: CN=g3,CN=users,DC=aforest,DC=ad CN=user4,CN=users,DC=aforest,DC=ad memberOf: CN=g4,CN=users,DC=aforest,DC=ad CN=user5,CN=users,DC=aforest,DC=ad memberOf: CN=g5,CN=users,DC=aforest,DC=ad And using this sssd.conf ------------------------------------------------------------------------------- [sssd] config_file_version = 2 services = nss, pam domains = aforest.ad [nss] [pam] [domain/aforest.ad] auth_provider = ad id_provider = ad access_provider = simple simple_allow_groups = g1 ldap_deref_threshold = 1 debug_level = 10 ------------------------------------------------------------------------------- In this setup sssd can't resolve group 'g1' because it fails parsing one of the referenced members, 'g3': $> getent group g1 No output. $> id user5 uid=1862001108(user5) gid=1862000513(domain users) groups=1862000513(domain users),1862001111,18620011 When the group is used to filter access it does not work: ...
