Doc Text:	Users of the lasso packages could previously experience several problems related to Red Hat Enterprise Linux interoperability with Microsoft Active Directory Federation Services (ADFS). Authentication against ADFS failed when using the mod_auth_mellon module. In addition, in Apache sessions, the limit for the number of elements was insufficient and multi-value variables were not supported. Also, the MellonCond parameter did not work when used together with the MellonSetEnv(NoPrefix) parameter. This update fixes the above described problems with ADFS interoperability.

Description Jarek Polok 2014-11-05 09:52:49 UTC

Current lasso release (2.4.0 on 6.6 and 2.4.1(?) on upcoming 7.1) needs xml xsd:choices patches for Microsoft ADFS interoperability. Without these attempts to authenticate using mod_auth_mellon against our ADFS setup result in "Error processing authn response. Lasso error: [-427] When looking for an assertion we did not found it., referer [...]"

Patches from upstream lasso git:

http://repos.entrouvert.org/lasso.git/commit/?id=4ad4b673940ef72de1a62d7589cd0d86290086b1

http://repos.entrouvert.org/lasso.git/commit/?id=a27d1686b387a045607b5f0802001ea8863342cb

(Above patches are to be included in upcoming lasso 2.4.2 release.)

Patches apply cleanly to current lasso 2.4.0 and and fix 'assertion not found' problem.

Please consider including in next lasso update,

Thanks !

Jarek
