[BUG] rest_cherrypy fails wheel auth with token #63927

Open nf-brentsaner opened 1 year ago

nf-brentsaner commented 1 year ago

Description Try as I might, rest_cherrypy fails to auth properly for wheel commands when using a token. (And returns a 500 instead of a 401.)

Setup (some values replaced with facsimiles)

master config ```yaml rest_cherrypy: port: 8000 host: 127.0.0.1 log_access_file: /var/log/salt/api.access.log log_error_file: /var/log/salt/api.error.log disable_ssl: True debug: True static: /srv/http/salt_api auth.ldap.server: SOME.CORPDOMAIN.TLD auth.ldap.port: 389 auth.ldap.tls: False auth.ldap.starttls: False auth.ldap.scope: 2 auth.ldap.no_verify: True auth.ldap.anonymous: False auth.ldap.activedirectory: True auth.ldap.persontype: 'person' auth.ldap.basedn: 'dc=domain,dc=tld' auth.ldap.binddn: "{{ username }}@SOME.CORPDOMAIN.TLD" auth.ldap.accountattributename: 'sAMAccountName' auth.ldap.auth_by_group_membership_only: False auth.ldap.groupclass: 'group' auth.ldap.groupattribute: 'memberOf' external_auth: ldap: Corp Engineers%: - .* - '@wheel' - '@runner' - '@jobs' 'Corp Technicians%': - '*': - 'state.apply' - 'test.ping' ext_pillar: - saltsources: [] - file_tree: root_dir: '/srv/salt/sys/_pillars/files' follow_dir_links: False keep_newline: True user: saltstack group: saltstack pidfile: /var/run/salt/master.pid log_level: warning log_level_logfile: debug minion_data_cache: False use_superseded: - module.run interface: '::' ipv6: True timeout: 15 show_jid: True strip_colors: False cli_summary: True fileserver_backend: - roots - gitfs file_roots: base: - /srv/salt/sys - /srv/salt/winpkg gitfs_provider: pygit2 pillar_roots: base: - /srv/salt/sys/_pillars - /srv/salt/winpkg/_pillars ext_pillar_first: True module_dirs: - /srv/salt/_meta/lib extension_modules: None keysize: 4096 sign_pub_messages: True hash_type: sha512 failhard: False roster: saltsources ssh_port: 22 ssh_scan_ports: 22 ssh_scan_timeout: 0.5 ssh_sudo: False ssh_run_pre_flight: True ssh_timeout: 60 ssh_user: root ssh_use_home_key: True roster_defaults: user: root sudo: False priv: /var/lib/saltstack/.ssh/id_ed25519 tty: True ssh_options: - StrictHostKeyChecking=accept-new - ChallengeResponseAuthentication=no - KexAlgorithms=curve25519-sha256@libssh.org,diffie-hellman-group-exchange-sha256 - Ciphers=chacha20-poly1305@openssh.com,aes256-gcm@openssh.com,aes128-gcm@openssh.com,aes256-ctr,aes192-ctr,aes128-ctr - MACs=hmac-sha2-512-etm@openssh.com,hmac-sha2-256-etm@openssh.com,umac-128-etm@openssh.com,hmac-sha2-512,hmac-sha2-256,umac-128@openssh.com - HostKeyAlgorithms=ssh-ed25519-cert-v01@openssh.com,ssh-rsa-cert-v01@openssh.com,ssh-ed25519,ssh-rsa winrepo_remotes: [] winrepo_provider: pygit2 winrepo_dir_ng: /srv/salt/winpkg/win/repo-ng winrepo_pubkey: /var/local/saltstack/.ssh/winrepo_ecdsa.pub winrepo_privkey: /var/local/saltstack/.ssh/winrepo_ecdsa winrepo_remotes_ng: - https://github.com/saltstack/salt-winrepo-ng.git - git@github.com:corpgit/winrepo-ng.git ```

Please be as specific as possible and give set-up details.

Steps to Reproduce the behavior Refer to above master log and nginx config.

Reverse-proxy to salt-api via Nginx using above configuration.

Use LDAP auth to AD.

Tomfoolery ensues. Assume that ${user} below is indeed a member of Corp Engineers, and per the master debug log is properly detected as such.

Getting a token succeeds. ```bash token_out=$(curl -sL \ -H "Accept: application/json" \ -d username="${uname}" \ -d password="${passwd}" \ -d eauth="ldap" \ "https://domain.tld/login") token=$(echo "${token_out}" | jq -r .return[0].token) ```
and SOME endpoints work fine... ```bash curl -sSL \ -H "Accept: application/json" \ -H "X-Auth-Token: ${token}" \ "https://domain.tld/stats" | jq . ```
...and some calls, like `/keys`, fail catastrophically if... `X-Auth-Token` is used: ``` curl -sSL \ -o /tmp/keygen/minionkeys.tar \ -H "Accept: application/x-tar" \ -d mid="minion_id_name" \ -H "X-Auth-Token: ${token}" \ "https://domain.tld/keys" #### 500 Internal Server Error

``` But succeeds for `eauth`. ``` curl -sSL \ -o /tmp/keygen/minionkeys.tar \ -H "Accept: application/x-tar" \ -d mid="minion_id_name" \ -d username="${uname}" \ -d password="${passwd}" \ -d eauth="ldap" \ "https://domain.tld/keys" ``` ```bash $ file minionkeys.tar minionkeys.tar: POSIX tar archive ```

Expected behavior A valid token should work for e.g. @wheel endpoints provided permissions allow for it.
