Fixed In Version:	389-ds-base-1.3.1.2-1.el7	Doc Type:	Enhancement
Doc Text:	Cause: Lack of being able to check multiple matching SASL mappings if one mapping should fail. Consequence: Rigid use of SASL authentication. Change: Added SAL mapping fallback/failover capability. As well as an optional priority/precedence for each mappings. Result: SASL authentication is more robust. What now happens when the actions or circumstances above occur. Note: this is not the same as the feature request was fulfilled.	Story Points:	---

Description Nathan Kinder 2013-03-06 18:16:01 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/534

Currently once a SASL mapping regex matches, the server attempts to find an entry in the directory as configure within the matched rule.
If no entry is found then the mapping fails.

It would be useful if a missing mapping would cause DS to try the next matching SASL mapping.

This enhancement would allow FreeIPA to fix https://fedorahosted.org/freeipa/ticket/3291

Comment 1 Rich Megginson 2013-10-01 23:25:10 UTC

moving all ON_QA bugs to MODIFIED in order to add them to the errata (can't add bugs in the ON_QA state to an errata).  When the errata is created, the bugs should be automatically moved back to ON_QA.

Feature is implemented in latest RHEL7 389, testing is yet to be done - bugs in this feature will be filed separately.
