* 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 https://fedorahosted.org/freeipa/ticket/2095
* Increase the session ID from 48 random bits to 128. * Implement the sesison_logout RPC command. It permits the UI to send a command that destroys the users credentials in the current session. * Restores the original web URL's and their authentication protections. Adds a new URL for sessions /ipa/session/json. Restores the original Kerberos auth which was for /ipa and everything below. New /ipa/session/json URL is treated as an exception and turns all authenticaion off. Similar to how /ipa/ui is handled. * Refactor the RPC handlers in rpcserver.py such that there is one handler per URL, specifically one handler per RPC and AuthMechanism combination. * Reworked how the URL names are used to map a URL to a handler. Previously it only permitted one level in the URL path hierarchy. We now dispatch on more that one URL path component. * Renames the api.Backend.session object to wsgi_dispatch. The use of the name session was historical and is now confusing since we've implemented sessions in a different location than the api.Backend.session object, which is really a WSGI dispatcher, hence the new name wsgi_dispatch. * Bullet-proof the setting of the KRB5CCNAME environment variable. ldap2.connect already sets it via the create_context() call but just in case that's not called or not called early enough (we now have other things besides ldap which need the ccache) we explicitly set it early as soon as we know it. * Rework how we test for credential validity and expiration. The previous code did not work with s4u2proxy because it assumed the existance of a TGT. Now we first try ldap credentials and if we can't find those fallback to the TGT. This logic was moved to the KRB5_CCache object, it's an imperfect location for it but it's the only location that makes sense at the moment given some of the current code limitations. The new methods are KRB5_CCache.valid() and KRB5_CCache.endtime(). * Add two new classes to session.py AuthManager and SessionAuthManager. Their purpose is to emit authication events to interested listeners. At the moment the logout event is the only event, but the framework should support other events as they arise. * Add BuildRequires python-memcached to freeipa.spec.in * Removed the marshaled_dispatch method, it was cruft, no longer referenced. https://fedorahosted.org/freeipa/ticket/2362
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.
This creates a new container, cn=s4u2proxy,cn=etc,$SUFFIX Within that container we control which services are allowed to delegate tickets for other services. Right now that is limited from the IPA HTTP to ldap services. Requires a version of mod_auth_kerb that supports s4u2proxy https://fedorahosted.org/freeipa/ticket/1098
This patch broke installation of a new master. Reverting until we develop a better solution. This reverts commit f42da4357eac7e64e803b53c78d6cff9175d20a4.
This also corrects a slight bug where if add is True then we always re-update the file. https://fedorahosted.org/freeipa/ticket/1755
- Remove ipa-pki-proxy.conf when IPA is uninstalled - Move file removal to httpinstance.py and use remove_file() - Add a version stanza - Create the file if it doesn't exist on upgraded installs https://fedorahosted.org/freeipa/ticket/1771
Dogtag is going to be proxied through httpd. To make this work, it has to support renegotiation of the SSL connection. This patch enables renegotiate in the nss configuration file during during apache configuration, as well as modifies libnss to set the appropriate optins on the ssl connection in order to renegotiate. The IPA install uses the internal ports instead of proxying through httpd since httpd is not set up yet. IPA needs to Request the certificate through a port that uses authentication. On the Dogtag side, they provide an additional mapping for this: /ca/eeca/ca as opposed tp /ca/ee/ca just for this purpose. https://fedorahosted.org/freeipa/ticket/1334 add flag to pkicreate in order to enable using proxy. add the proxy file in /etc/http/conf.d/ Signed-off-by: Simo Sorce <ssorce@redhat.com>
