I'm trying to setup sudo-ldap in a clean CentOS 7 docker environment. I've successfully setup sssd and PAM authentication, and it works.

However, sudo-ldap works only if !authenticate is set:

dn: cn=test,ou=SUDOers,ou=People,dc=srv,dc=world objectClass: top objectClass: sudoRole cn: test sudoUser: test sudoHost: ALL sudoRunAsUser: ALL sudoCommand: ALL sudoCommand: !/bin/cp sudoOption: !authenticate

When I run sudo cp, I got the following debug logs:

# without !authenticate sudo: searching LDAP for sudoers entries sudo: ldap sudoRunAsUser 'ALL' ... MATCH! sudo: ldap sudoCommand 'ALL' ... MATCH! sudo: ldap sudoCommand '!/bin/cp' ... MATCH! sudo: Command allowed sudo: LDAP entry: 0x55ed4d71b930 sudo: done with LDAP searches sudo: user_matches=true sudo: host_matches=true sudo: sudo_ldap_lookup(0)=0x02 [sudo] password for test: Sorry, try again. # with !authenticate sudo: searching LDAP for sudoers entries sudo: ldap sudoRunAsUser 'ALL' ... MATCH! sudo: ldap sudoCommand 'ALL' ... MATCH! sudo: Command allowed sudo: LDAP entry: 0x564d56cb9960 sudo: done with LDAP searches sudo: user_matches=true sudo: host_matches=true sudo: sudo_ldap_lookup(0)=0x02 sudo: removing reusable search result cp: missing file operand Try 'cp --help' for more information.

I can use the password to login via SSH, but not able to run sudo command, does anyone know what's wrong?

Attached /etc/pam.d/system-auth (sudo is including that file)
