I’m currently working on deploying OpenLDAP and SSSD for authentication. When I try to id a user that is stored within LDAP I get the response no such user.

The user has been added to LDAP correctly and I can perform an ldapsearch –ZZ and find the user.

I have tried running sssd –i –d9 and get the following response when trying to id the user:

The hostname hostname resolves, the port 636 is definitely open (have turned iptables off and also able to telnet)

The following is my sssd config file:

[sssd]
config_file_version = 2
services = nss, pam
domains = LDAP

[nss]
filter_users = root, ldap, named

[pam]

# LDAP domain
[domain/LDAP]

ldap_tls_reqcert = demand
auth_provider = ldap
ldap_schema = rfc2307bis
ldap_search_base = dc=test,dc=domain
ldap_group_member = uniquemember
id_provider = ldap
ldap_id_use_start_tls = true
chpass_provider = ldap
ldap_uri = ldaps://hostname:636/
ldap_chpass_uri = ldaps://hostname:636/
cache_credentials = true
ldap_tls_cacertdir = /etc/openldap/cacerts/
ldap_tls_cacert = /etc/openldap/cacerts/cacert.pem
entry_cache_timeout = 600
ldap_network_timeout = 3
ldap_access_filter = (&(object)(object))

I have been unsuccessful in finding answers in Google. Any pointers towards a solution would be greatly appreciated.

Many Thanks.

  • Please add an example LDAP object in the question.

ldap_id_use_start_tls = true

is definitely wrong.

In order to crypt your network traffic to LDAP you have to choices:

  • Older SSL on port 636
  • Newer StartTLS on port 389 (connection starts in plain then upgrades to TLS)

StartTLS and SSL are mutally exclusive.

Try removing the offending line.

ldap_access_filter looks weird. Try without it.
