Sudo LDAP stopped working in 1.9.15 #325
Description
Sudo LDAP was working for me with 1.9.14.p3, but broke with 1.9.15 on my setup and I haven't been able to determine why.
When I do sudo -ll with SUDOERS_DEBUG 2 in 1.9.14.p3 I get LDAP debug output indicating the correct things are happening, but with 1.9.15 there's no LDAP debug output at all. I simply get a password prompt followed by "not in sudoers file" and no indication LDAP is being queried. Reverting to 1.9.14.p3 restores the expected behavior.
I'm not sure if this is an Arch packaging issue, sudo regression, or config issue on my end. Here's my relevant configs and LDAP objects. Please let me know if more info is needed to diagnose.
/etc/nsswitch.conf:
# ...
sudoers: files ldap
# ...(I tried swapping ldap and files but same result, and I prefer it checks local first anyway.)
/etc/sudo.conf:
Plugin sudoers_policy sudoers.so
Plugin sudoers_io sudoers.so
Plugin sudoers_audit sudoers.so ldap_secret=/path/to/ldap-password
(That's the entirety of sudo.conf and I must admit I don't fully understand it but it worked for me in < 1.9.15.)
/etc/openldap/ldap.conf:
URI ldapi://%2frun%2fopenldap%2fslapd.sock
BASE o=home
ROOTBINDDN cn=sudo,ou=roles,o=home
SUDOERS_BASE o=home
SUDOERS_DEBUG 2
(Perhaps sudo is looking for ldap.conf in a different place now? I'm not sure how to figure out where it checks but if that's the case it could be a packaging issue...)
