The LDAP attribute has SYNTAX 1.3.6.1.4.1.1466.115.121.1.7 (a binary attribute) and I’ve checked I can set that to TRUE / FALSE appropriately.

The JSON it gets for the UserRepresentation on the client side is “enabled”:true which explains the state of the toggle.

Notably, I can setup LDAP attribute mappers for the enabled (boolean), emailVerified (boolean), and requiredActions (Set<String>) model fields and they work as expected. I did not need to store TOTP, it seems to just work but if I’m missing a scenario where it doesn’t, the same approach should work. Required Actions caused me a bit of effort. It does not have a setter on the proxy like the others, instead is has addRequiredAction/removeRequiredAction mutator methods. This means I’ve had to detect the requiredAction model field in a couple of areas to short-circuit so that errors don’t crop up in the logs. It’s still functional without those short-circuits (as Required Actions are handled later in the processes) but the logs can get noisy and confusingly point to a problem that’s not there. Personally I think it’s cleaner to short-circuit. [If I’m not being clear, I can try to explain again differently.] Because of my unfamiliarity with Github, I’ve ended up opening a Draft Pull Request. I wanted to do it within my own fork, but ended up doing it live. I’ve left it so you can see where I’m up to. A quick review of my approach would be very welcome as I’ve never committed to Keycloak before and would appreciate a nod that I’m going in the right direction with all this. https://github.com/keycloak/keycloak/pull/5908 I have no automated tests yet, it’s just been a manual development cycle as it was slow enough getting up to speed with the code base, let alone the LDAP side of the test harness! I’ll move onto that next and hopefully with that and completing the rest of the committer guidance, it’ll be soon accepted! — Dan Hardiker | Adaptavist dhardiker(a)adaptavist.com Winners of the Atlassian President's Award for Technical Excellence - http://bit.ly/techexc Adaptavist, Waterside, Unit 2, 44-48 Wharf Road, London, N1 7UX, United Kingdom.

I’ve found that boolean fields sometimes map inversely to common LDAP attributes one might choose to back Keycloak with (e.g. UserModel.enabled <> LDAPUser.loginDisabled). Would it be ok to add another setting to the UserAttributeLDAPStorageMapper which would be “Invert boolean values” - so an UserModel.enabled == true maps to setting LDAPUser.loginDisabled = false? If so, any tips on where the areas to extend that in, beyond the Mapper itself (I’m thinking at least a theme or two?). > > Thanks for the continued support, I’m starting to feel a little more comfortable with the Keycloak codebase. > > > — > Dan Hardiker | Adaptavist > dhardiker(a)adaptavist.com > > Winners of the Atlassian President's Award for Technical Excellence - http://bit.ly/techexc > > Adaptavist, Waterside, Unit 2, 44-48 Wharf Road, London, N1 7UX, United Kingdom. > Registered in England and Wales #5456785. > >> On 20 Feb 2019, at 13:03, Marek Posolda <mposolda(a)redhat.com&gt; wrote: >> >> On 18/02/2019 18:39, Dan Hardiker wrote: >>> Hi All, >>> >>> Sorry for such a long first post.
