[CLAassistant]

All committers have signed the CLA.

[ajjonen]

A lot of failed tests here.

[fdrab]

yes, will look at what's wrong soon

[fdrab]

the failing check is due to st2-ldap-auth failing sha checksum after download. not for me to fix.

[fdrab]

regarding CLA I was also the person that committed the initial commits. how do I fix that?

[nzlosh]

@fdrab You'll need to amend the commits with the correct email address in the branch and force push to update. Information on how to amend commits here (interactive would probably be the easiest approach) here https://www.git-tower.com/learn/git/faq/change-author-name-email/

[fdrab]

I've made a mess of things by not force pushing, but hopefully this is OK now. let me know if I need to do anything more

[ajjonen]

I am for just merging this. The requirements changes are clouding it a bit and can be fixed after.

@ajjonen are you able to approve with @guzzijones account as that is the one official recognised as a StackStorm maintainer.
