Prevent the SimpleSAML_Logger class from creating loops while trying to get the track ID from the session. It must now be set manually by calling SimpleSAML_Logger::setTrackID(). Also allow SimpleSAML_Memcache to differentiate between a key not found in memcache and a request to memcache failed. If all servers are down, an exception is thrown and the user informed about the internal error. This hopefully resolves #264.

Corrected typo in core:show_metadata template

Prevent data-collision when hosting several SSP-instances on one machine, when more than one is using memcache.

Introduces new config setting 'memcache_store.prefix'.

Deprecate the 'userid.attribute' option. We should define specific options for each module using it, in order to avoid confussions.

Set trusted.url.domains default to array()

Bugfix: if there's no session, getCookieSessionId() cannot return a session identifier, therefore there's no session we can return. This resolves #256.

  Update LDAP.php

Update LDAP.php

Fixed to follow PSR-2 coding guidelines, proper indentation and a minor fix in equality operand (== vs ===)

Update Negotiate.php

This commit addresses Issue 268 and makes the negotiate module a bit more configurable, like the ldap-module it's leaning on..
