b8b573a966 Deprecate HBAC source hosts from CLI
Hide the commands and options listed below from the CLI,
but keep them in the API. When called directly from the API,
raise appropriate exceptions informing the user that the
functionality has been deprecated.

Affected commands: hbacrule_add_sourcehost, hbacrule_remove_sourcehost.
Affected options: sourcehostcategory, sourcehost_host and
sourcehost_hostgroup (hbacrule); sourcehost (hbactest).

664248d5b8 Use IPAdmin rather than raw python-ldap in migration.py and ipadiscovery.py
These used ipautil.get_ipa_basedn. Convert that to use the new wrappers.

Beef up the error handling in ipaldap to accomodate the errors we catch
in the server discovery.
Add a DatabaseTimeout exception to errors.py.

These were the last uses of ipautil.convert_ldap_error, remove that.

8af5369cba Add ipalib.messages
The messages module contains message classes that can be added
to a RPC response to provide additional information or warnings.

This patch adds only the module with a single public message,
VersionMissing, and unit tests.
Since message classes are very similar to public errors, some
functionality and unit tests were shared.

a1991aeac1 Use secure method to acquire IPA CA certificate
Major changes ipa-client-install:

* Use GSSAPI connection to LDAP server to download CA cert (now
  the default method)

* Add --ca-cert-file option to load the CA cert from a disk file.
  Validate the file. If this option is used the supplied CA cert
  is considered definitive.

* The insecure HTTP retrieval method is still supported but it must be
  explicitly forced and a warning will be emitted.

* Remain backward compatible with unattended case (except for aberrant
  condition when preexisting /etc/ipa/ca.crt differs from securely
  obtained CA cert, see below)

* If /etc/ipa/ca.crt CA cert preexists the validate it matches the
  securely acquired CA cert, if not:

  - If --unattended and not --force abort with error

  - If interactive query user to accept new CA cert, if not abort

  In either case warn user.

* If interactive and LDAP retrieval fails prompt user if they want to
  proceed with insecure HTTP method

* If not interactive and LDAP retrieval fails abort unless --force

* Backup preexisting /etc/ipa/ca.crt in FileStore prior to execution,
  if ipa-client-install fails it will be restored.

Other changes:

* Add new exception class CertificateInvalidError

* Add utility convert_ldap_error() to ipalib.ipautil

* Replace all hardcoded instances of /etc/ipa/ca.crt in
  ipa-client-install with CACERT constant (matches existing practice
  elsewhere).

* ipadiscovery no longer retrieves CA cert via HTTP.

* Handle LDAP minssf failures during discovery, treat failure to check
  ldap server as a warninbg in absebce of a provided CA certificate via
  --ca-cert-file or though existing /etc/ipa/ca.crt file.

173ee4d141 Switch %r specifiers to '%s' in Public errors
This switch drops the preceding 'u' from strings within Public error messages.

This patch also addresses the related unfriendly 'u' from re-raising errors from netaddr.IPAddress by passing a bytestring through the function.

Also switched ValidationError to TypeError in validate_scalar per jcholast@redhat.com.

supply instructions parameter to a class derived from PublicError.

This will cause following text added to the error message:

941d1e8701 Do not produce unindexed search on every DEL command
Every <plugin>-del command executes an "(objectclass=*)" search
to find out if a deleted node has any child nodes which would need
to be deleted first. This produces an unindexed search for every del
command which biases access log audits and may affect performance too.

Since most of the *-del commands delete just a single object (user,
group, RBAC objects, SUDO or HBAC objects, ...) and not a tree
(automount location, dns zone, ...) run a single entry delete first
and only revert to subtree search&delete when that fails.

a95eaeac8e Internationalization for public errors
Currently, we throw many public exceptions without proper i18n.
Wrap natural-language error messages in _() so they can be translated.

In the service plugin, raise NotFound errors using handle_not_found helper
so the error message contains the offending service.

Use ScriptError instead of NotFoundError in bindinstance install.

4f03aed5e6 prevent last admin from being disabled
We prevent the last member of the admin group from being deleted. The
same check needs to be performed when disabling a user.

* Moved the code in del_user to the common subroutine
  check_protected_member() and call it from both user_del and
  user_disable. Note, unlike user_del user_disable does not have a
  'pre' callback therefore the check function is called in
  user_disable's execute routine.

* Make check_protected_member() aware of disabled members. It's not
  sufficient to check which members of the protected group are
  present, one must only consider those members which are enabled.

* Add tests to test_user_plugin.py.

  - verify you cannot delete nor disable the last member of the admin
    group

  - verify when the admin group contains disabled users in addition to
    enabled users only the enabled users are considered when
    determining if the last admin is about to be disabled or deleted.

* Replace duplicated hardcoded values in the tests with variables or
  subroutines, this makes the individual tests a bit more succinct and
  easier to copy/modify.

* Update error msg to reflect either deleting or disabling is an error.

ee780df13c Implement password based session login
* Adjust URL's
  - rename /ipa/login -> /ipa/session/login_kerberos
  - add /ipa/session/login_password

* Adjust Kerberos protection on URL's in ipa.conf

* Bump VERSION in httpd ipa.conf to pick up session changes.

* Adjust login URL in ipa.js

* Add InvalidSessionPassword to errors.py

* Rename krblogin class to login_kerberos for consistency with
  new login_password class

* Implement login_password.kinit() method which invokes
  /usr/bin/kinit as a subprocess

* Add login_password class for WSGI dispatch, accepts POST
  application/x-www-form-urlencoded user & password
  parameters. We form the Kerberos principal from the server's
  realm.

* Add function  krb5_unparse_ccache()

* Refactor code to share common code

* Clean up use of ccache names, be consistent

* Replace read_krbccache_file(), store_krbccache_file(), delete_krbccache_file()
  with load_ccache_data(), bind_ipa_ccache(), release_ipa_ccache().
  bind_ipa_ccache() now sets environment KRB5CCNAME variable.
  release_ipa_ccache() now clears environment KRB5CCNAME variable.

* ccache names should now support any ccache storage scheme,
  not just FILE based ccaches

* Add utilies to return HTTP status from wsgi handlers,
  use constants for HTTP status code for consistency.
  Use utilies for returning from wsgi handlers rather than
  duplicated code.

* Add KerberosSession.finalize_kerberos_acquisition() method
  so different login handlers can share common code.

* add Requires: krb5-workstation to server (server now calls kinit)

* Fix test_rpcserver.py to use new dispatch inside route() method

efb37739ab Add common helper for interactive prompts
This patch adds a common method, textui.prompt_helper, that handles
encoding, decoding and error handling for interactive prompts.
On EOFError (Ctrl+D) or  KeyboardInterrupt (Ctrl+C), it raises
a new InvocationError, PromptFailed.

The helper is used in prompt, prompt_yesno, and prompt_password,
each of which originally only handled one of Ctrl+C and Ctrl+D.
This fixes https://fedorahosted.org/freeipa/ticket/2345
And it means prompt_yesno will no longer return None on error.

A minor fix restores errors.py's ability print out the list of
errors when run as a script.

bba4ccb3a0 add session manager and cache krb auth
This patch adds a session manager and support for caching
authentication in the session. Major elements of the patch are:

* Add a session manager to support cookie based sessions which
  stores session data in a memcached entry.

* Add ipalib/krb_utils.py which contains functions to parse ccache
  names, format principals, format KRB timestamps, and a KRB_CCache
  class which reads ccache entry and allows one to extract information
  such as the principal, credentials, credential timestamps, etc.

* Move krb constants defined in ipalib/rpc.py to ipa_krb_utils.py so
  that all kerberos items are co-located.

* Modify javascript in ipa.js so that the IPA.command() RPC call
  checks for authentication needed error response and if it receives
  it sends a GET request to /ipa/login URL to refresh credentials.

* Add session_auth_duration config item to constants.py, used to
  configure how long a session remains valid.

* Add parse_time_duration utility to ipalib/util.py. Used to parse the
  session_auth_duration config item.

* Update the default.conf.5 man page to document session_auth_duration
  config item (also added documentation for log_manager config items
  which had been inadvertantly omitted from a previous commit).

* Add SessionError object to ipalib/errors.py

* Move Kerberos protection in Apache config from /ipa to /ipa/xml and
  /ipa/login

* Add SessionCCache class to session.py to manage temporary Kerberos
  ccache file in effect for the duration of an RPC command.

* Adds a krblogin plugin used to implement the /ipa/login
  handler. login handler sets the session expiration time, currently
  60 minutes or the expiration of the TGT, whichever is shorter. It
  also copies the ccache provied by mod_auth_kerb into the session
  data.  The json handler will later extract and validate the ccache
  belonging to the session.

* Refactored the WSGI handlers so that json and xlmrpc could have
  independent behavior, this also moves where create and destroy
  context occurs, now done in the individual handler rather than the
  parent class.

* The json handler now looks up the session data, validates the ccache
  bound to the session, if it's expired replies with authenicated
  needed error.

* Add documentation to session.py. Fully documents the entire process,
  got questions, read the doc.

* Add exclusions to make-lint as needed.

4ad8055341 Re-implement access control using an updated model.
The new model is based on permssions, privileges and roles.
Most importantly it corrects the reverse membership that caused problems
in the previous implementation. You add permission to privileges and
privileges to roles, not the other way around (even though it works that
way behind the scenes).

A permission object is a combination of a simple group and an aci.
The linkage between the aci and the permission is the description of
the permission. This shows as the name/description of the aci.

ldap:///self and groups granting groups (v1-style) are not supported by
this model (it will be provided separately).

This makes the aci plugin internal only.

A host in DNS must have an IP address so a valid IP address is required
when adding a host. The --force flag will be needed too since you are
adding a host that isn't in DNS.

For IPv4 it will create an A and a PTR DNS record.

IPv6 isn't quite supported yet. Some basic work in the DNS installer
is needed to get this working. Once the get_reverse_zone() returns the
right value then this should start working and create an AAAA record and
the appropriate reverse entry.

When deleting a host with the --updatedns flag it will try to remove all
records it can find in the zone for this host.
