Block a user
Delete Branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Originally created by @rem9000 on GitHub (Feb 24, 2021).
I'm getting this error after logging in:
It says: An user with this email address already exists.
I'm using LDAP and changed my password in active directory.
(newest bookstack release)

i am just now logging in, and i have EXACTLY the same problem.
Unfortunately, on our end nothing changed. it just "stopped working" as far as i can see. the \storage\logs\laravel.log" show exactly the same error.
@rem9000 commented on GitHub (Feb 24, 2021):
Have you fixed it yet? If so how? 😄
@ssddanbrown commented on GitHub (Feb 25, 2021):
@remkohoef Did this user, with that email address, already have an BookStack account before LDAP was setup/enabled?
@rem9000 commented on GitHub (Feb 25, 2021):
No. We have 1 "local" admin account. Then we set-up LDAP a long while ago and all the users were created via LDAP.
My colleague has the same problem as @jhjacobs81 .. He didn't change his password and is not able to logon. This problem occurred the day before yesterday. Nothing has changed in the past days. Yesterday I updated bookstack with no result.
@rem9000 commented on GitHub (Feb 25, 2021):
Seems like bookstack turned all ldap users to bookstack users because when I set login method to standard we can log in with the email address connected to the account.
@cdrfun commented on GitHub (Feb 25, 2021):
When a user signs in via LDAP a Bookstack user is created which has an external authentication id.
When a user was created prior to LDAP configuration this user doesn't have an external authentication id. Your problem sounds to me, as if a user was created with a mail address, then LDAP was activated and now Bookstack tries to create a new user upon login with the same mail address - which leads to the error that the mail already exists (for the first user with no external authentication id). This is also explained here: https://www.bookstackapp.com/docs/admin/ldap-auth/
The solution provided in the documentation is:
Another solution would be to change AUTH_METHOD to standard, change the mail address of the first user, set "Default user role after registration" to Admin, change AUTH_METHOD to LDAP, register with new user and change "Default user role after registration" back.
A third way would be to add the external authentication id to the user using a database query.
@rem9000 commented on GitHub (Feb 25, 2021):
No, all users were created with LDAP. We didn't have any email users (except 1 admin account).
Everything worked fine until a few days ago when we suddenly couldn't log on anymore.
@rem9000 commented on GitHub (Feb 25, 2021):
Ok, so my problem was that we moved some users in AD, that way the External Authentication ID was not right anymore.

When using Authentik with OIDC, I changed the
Subject modefrombased on the user's hashed IDtobased on the user's email. I also copied the email into the "External Authentication ID", and it seems like a bit of a hassle to remove it/change it. Either way, it did the trick for me.
