Many thanks for the help,
We have updated the version of SSSD we are using to be:
1.5.15-0ubuntu6~lucid2
I’ve set up our domain (EEMEA) with:
access_provider = ldap
ldap_access_order = filter
and an empty ldap_access_filter
The logs suggest that this will deny any domain users who try to log on:
(Wed Jan 16 14:25:14 2013) [sssd[be[EEMEA]]] [sssm_ldap_access_init] (0): Warning: LDAP
access rule 'filter' is set, but no ldap_access_filter configured. All domain
users will be denied access.
However, this doesn’t bear out in reality:
(Wed Jan 16 14:25:19 2013) [sssd[be[EEMEA]]] [be_pam_handler] (4): Got request with the
following data
(Wed Jan 16 14:25:19 2013) [sssd[be[EEMEA]]] [pam_print_data] (4): command:
PAM_AUTHENTICATE
.....
(Wed Jan 16 14:25:20 2013) [sssd[be[EEMEA]]] [be_pam_handler_callback] (4): Backend
returned: (0, 0, <NULL>) [Success]
We normally have the following in our config:
cache_credentials = TRUE
enumerate = TRUE
I’ve also tried with these values set to False, with the same results.
I’ve also tried:
access_provider = deny
and
access_provider = simple
simple_allow_users = bob
logging in as peter still succeeds, in both cases.
Any hints? Is this a problem with our config or this version of SSSD?
Many thanks for the help
Dan
This is a problem with your config. The authentication step is expected
to succeed. The denial should be happening during pam_acct_mgmt() which
is later in the stack. I'm guessing your PAM stack is missing
pam_sss.so in the 'account' stack.
