A new user is not automatically added to the group

[FedorShlein]

Hi everyone! Unfortunately I encountered an error when a new user cannot automatically get into the group after self-registration.
The user registers in the system, but does not get any group, although in the settings it is set that after registration he should get into the guests' group.
Authentication strategy: LDAP
OS: Ubuntu 22.04/24.04 started the problem on 22.04 after some update, after moving the base to 24.04 the problem remained, so I assume that the problem is in the base or execution of some script.
Base: pgsql 14.12/16
Node: 16/18

I have enabled LDAP logging, however, there was no output of value to determine the issue

I attach the error in text:
insert into "userGroups" ("groupId", "userId") values ($1, $2), ($3, $4) returning "groupId" - insert or update on table "userGroups" violates foreign key constraint "usergroups_groupid_foreign"

In systemd the error looks like this:
warn: LDAP LOGIN ERROR (c2): insert into "userGroups" ("groupId", "userId") values ($1, $2), ($3, $4) returning "groupId>
