* Make token auth and sync windows configurableNathaniel McCallum2014-12-056-151/+199
| | | | | | | | | | | This introduces two new CLI commands: * otpconfig-show * otpconfig-mod https://fedorahosted.org/freeipa/ticket/4511 Reviewed-By: Thierry Bordaz <tbordaz@redhat.com> Reviewed-By: Petr Vobornik <pvoborni@redhat.com>
* Enable last token deletion when password auth type is configuredNathaniel McCallum2014-12-031-70/+173
| | | | | | | | | | | Also, ensure that the last token check only executes on DNs/entries that are tokens. This resolves a large performance issue where a query was being performed to load all the user's tokens on every del/mod operation. https://fedorahosted.org/freeipa/ticket/4697 https://fedorahosted.org/freeipa/ticket/4719 Reviewed-By: Thierry Bordaz <tbordaz@redhat.com>

* Ensure that a password exists after OTP validationNathaniel McCallum2014-11-061-12/+14
| | | | | | | | | | | | | | Before this patch users could log in using only the OTP value. This arose because ipapwd_authentication() successfully determined that an empty password was invalid, but 389 itself would see this as an anonymous bind. An anonymous bind would never even get this far in this code, so we simply deny requests with empty passwords. This patch resolves CVE-2014-7828. https://fedorahosted.org/freeipa/ticket/4690 Reviewed-By: Alexander Bokovoy <abokovoy@redhat.com>

With this patch a new version is added which will return the full member list for groups and the full list of group memberships for a user.

* Add TOTP watermark supportNathaniel McCallum2014-07-251-73/+86
| | | | | | | | | | | | | | | | This prevents the reuse of TOTP tokens by recording the last token interval that was used. This will be replicated as normal. However, this patch does not increase the number of writes to the database in the standard authentication case. This is because it also eliminates an unnecessary write during authentication. Hence, this patch should be write-load neutral with the existing code. Further performance enhancement is desired, but is outside the scope of this patch. https://fedorahosted.org/freeipa/ticket/4410 Reviewed-By: Alexander Bokovoy <abokovoy@redhat.com>

| | | | | | | | | | | | | | A mixture of implicit and explicit tagging was being used and this caused a bug in retrieving the enctype number due to the way ber_scanf() loosely treat sequences and explicit tagging.

* keytab: Add new extended operation to get a keytab.Simo Sorce2014-06-261-0/+571
| | | | | | | | | | | | | | | | | | | | | | | | | | | This new extended operation allow to create new keys or retrieve existing ones. The new set of keys is returned as a ASN.1 structure similar to the one that is passed in by the 'set keytab' extended operation. Access to the operation is regulated through a new special ACI that allows 'retrieval' only if the user has access to an attribute named ipaProtectedOperation postfixed by the subtypes 'read_keys' and 'write_keys' to distinguish between creation and retrieval operation. For example for allowing retrieval by a specific user the following ACI is set on cn=accounts: (targetattr="ipaProtectedOperation;read_keys") ... ... userattr=ipaAllowedToPerform;read_keys#USERDN) This ACI matches only if the service object hosts a new attribute named ipaAllowedToPerform that holds the DN of the user attempting the operation.

| | | | | | | | | | | | | | | This reverts commit bfdbd3b6ad7c437e7dd293d2488b2d53f4ea7ba6. Forceful validation of password expiration date in a BIND pre-callback breaks LDAP password change extended operation as the password change is only allowed via authenticated (bound) channel. Passwords could be only changed via kadmin protocol. This change would thus break LDAP-only clients and Web UI password change hook.
