LDAP auth source sat61_rhel71	none

Description Jason Montleon 2014-10-09 14:54:53 UTC

Description of problem:
Trying to log in via corporate LDAP results in:
Errno::EACCES
Permission denied - connect(2)
app/models/auth_sources/auth_source_ldap.rb:162:in `search_for_user_entries'
app/models/auth_sources/auth_source_ldap.rb:39:in `authenticate'
app/models/user.rb:178:in `try_to_login'
app/controllers/users_controller.rb:72:in `login'
app/models/concerns/foreman/thread_session.rb:33:in `clear_thread'
lib/middleware/catch_json_parse_errors.rb:9:in `call'

Version-Release number of selected component (if applicable):
Satellite 6.0.4 on RHEL 7

How reproducible:
Always

Steps to Reproduce:
1. Set up Satellite 6.0.4
2. Configure corporate LDAP as an auth source
3. Try to log in with a valid account

Actual results:
fails to log in with error above

Expected results:
Successful login

Additional info:
Interestingly I did not hit this while setting up an AD source. running audit2allow gave this:

#!!!! This avc can be allowed using one of the these booleans:
#     nis_enabled, authlogin_nsswitch_use_ldap, passenger_can_connect_all
allow passenger_t ldap_port_t:tcp_socket name_connect;

setsebool -P authlogin_nsswitch_use_ldap on did seem to correct it.

Comment 1 RHEL Program Management 2014-10-09 15:13:05 UTC

Since this issue was entered in Red Hat Bugzilla, the release flag has been
set to ? to ensure that it is properly evaluated for this release.

Comment 3 Lukas Zapletal 2014-10-09 15:23:31 UTC

This is strange, are you sure it helped?

This is the denial I see with selinux enabled

Hello all,
