At USD we are connecting WeBWorK to Blackboard with LTI. With a little bit of poking around I set WeBWorK up to use both LTI and LDAP, so that students can log in directly with their school SSO account once their webwork account is created by logging in through Blackboard once.
The only hiccup so far has been with one person (a faculty member) whose email account listed on blackboard had a different username from his LDAP username (a mail alias), so that no matter what I called his webwork user he was only able to log in one way but not the other. We fixed it by changing his blackboard email address to not use the alias.
I'm also a little confused about what the grades passed back to Blackboard (in course grade mode) are calculated out of, since they seem rather low. Is it a percentage of all assigned homework sets, or all open/closed ones, or all closed ones, or something else?
We (Portland Community College, webwork.pcc.edu) use Brightspace (formerly D2L) as our LMS. Our fall term starts Sep 26, and I expect *some* faculty will be using WeBWorK via Brightspace single sign-on. Some faculty prefer not to use Brightspace at all; if they use WeBWorK they will use it the "old-fashioned" way. Our winter term starts January 9, and I expect that we will have grade pass back ready to use by then too.
We at Dalhousie (math and stat dept) are using webwork using LTI to
connect to brightspace lms. I have our second webwork server
in use for two first year courses - one with 800+ students and other with 400+ students. It is working well so far. We tried to get grade passback working with brightspace over the summer term and wasn't successful. Hopefully that will also start working on a future webwork release. Auto creation of accounts via LTI has been very useful for us for the large classes.
There was a change added to WeBWorK 2.12 a couple of weeks back intended to fix grade passback to D2L/Brightspace. I have the on-submit grade passback working on our instance of Brightspace, though I'm still having issues with the scheduled grade passback.
The University of North Dakota is using the LTI to connect to Blackboard. Auto enrollment is working great. Grade passback is working when students complete an attempt, but the mass update doesn't appear to be working properly (see this posting). I've not had time to dig into why that might be the case.
At American University, we started using LTI last month in order to connect WeBWorK to Blackboard. Our experience so far has been very positive.
We're enjoying not having to create accounts for our students. However, we have lost one lovely capability that we gained last semester: the ability for students to use the same password that they use for all other university services. Instead, students *must* log in via a link that we create on Blackboard (unless we give them passwords manually, which we're not going to do). The reason for this has nothing to do with any deficiency in BB or WW, but it might apply to some other campuses: We generally use LDAP for authentication, but someone in IT insists that BB must use Shibboleth. In order to work with BB, WW now uses Shibboleth, and thus not LDAP. At least, this is how things were explained to me.
Most students won't notice any deficiency. But teachers now need manually-assigned passwords if they want to be able to respond to WW-generated e-mail from students.
Side-benefit of using LTI: We used to require anyone using our WW server either to be on campus or to set up a VPN connection. LTI forced our IT people to make some changes that mean that this is no longer the case. That’s one fewer thing to go wrong.
I believe that no one is presently passing back grades to Blackboard, since most of us tend not to use the gradebook feature. We export grades to spreadsheets, just like in the old days.
When we have several sections of a coordinated course, we combine them into a single course on Blackboard. This means that within such a course, we must create "groups" of students manually, so that we can have a way of e-mailing individual sections. And we have to update these groups as our rosters evolve during the first two weeks of the semester. But the upside is that we can then link this combined course to a single WeBWorK course.
Within WW, we tried to indicate manually which students belonged to which physical section, so that we could easily extract grades by section. However, we found that every time students logged in from BB, this information was overwritten. But then our IT guy found a setting to tweak that fixes this.

Grade passback (homework) was tested successfully, but is not in active use.
We have been using the code which is now in the WW 2.15 branch (essentially a release candidate) for about 6 months. Sites which had issues when student names have special characters are encouraged to migrate to WW 2.15. (shameless plug) now or after the formal release.
