user_saml not working for owncloud-7.0beta

[jhaar]

Hi there

I just went to give it at go with owncloud-7.0.0beta1 and it doesn't work. I have successfully tested the local simplesamlphp is working by using the authentication tab: ie I successfully logged into the following using SAML

/simplesaml/module.php/core/authenticate.php?as=owncloud

...but I cannot get user_saml to work, it generates the following error when I click on the "SAML" login icon on the owncloud login page

SimpleSAML_Error_NoState: NOSTATE
Backtrace:
2 /var/www/simplesamlphp-1.11.0/lib/SimpleSAML/Auth/State.php:232 (SimpleSAML_Auth_State::loadState)
1 /var/www/simplesamlphp-1.11.0/modules/saml/www/sp/saml2-acs.php:54 (require)
0 /var/www/simplesamlphp-1.11.0/www/module.php:135 (N/A)

The ssp logfile contains

Jul 03 23:04:06 simplesamlphp DEBUG [f4a391ed9b] Saved state: '_03e0a99918462db5e084df01b09ffbf5bc65cfea31'
Jul 03 23:04:07 simplesamlphp DEBUG [06fa91c968] Loading state: '_03e0a99918462db5e084df01b09ffbf5bc65cfea31'

which does imply it saved state and loaded it - so I suppose there's been some code change in owncloud-7 that user_saml doesn't handle?

Thanks
