False positive LDAP Blocked users


Sometimes, when a developer pushes via Git command lines, the Gitlab user becomes LDAP Blocked even if the user is not blocked at all. FYI, our LDAP is Lotus Domino server.
It seems to be linked with timeouts and Gitlab performances see our issue : Huge performance issues

To unblock the user, we have to remove his LDAP identity and ask him to login again to gitlab.
Could you help us please?

Note: Is there a way to disable the LDAP blocking system as a workaround?

Thank you in advance.
