acl - Unable to obtain the class id type - column name class_id_type was not found

[zemirco]

Describe the bug

I'm trying to use Spring Security in combination with ACLs. I use PostgreSQL as my database and have used the schema from the Spring Security docs.

create table acl_sid(
        id bigserial not null primary key,
        principal boolean not null,
        sid varchar(100) not null,
        constraint unique_uk_1 unique(sid,principal)
);

create table acl_class(
        id bigserial not null primary key,
        class varchar(100) not null,
        constraint unique_uk_2 unique(class)
);

create table acl_object_identity(
        id bigserial primary key,
        object_id_class bigint not null,
        object_id_identity varchar(36) not null,
        parent_object bigint,
        owner_sid bigint,
        entries_inheriting boolean not null,
        constraint unique_uk_3 unique(object_id_class,object_id_identity),
        constraint foreign_fk_1 foreign key(parent_object)references acl_object_identity(id),
        constraint foreign_fk_2 foreign key(object_id_class)references acl_class(id),
        constraint foreign_fk_3 foreign key(owner_sid)references acl_sid(id)
);

create table acl_entry(
        id bigserial primary key,
        acl_object_identity bigint not null,
        ace_order int not null,
        sid bigint not null,
        mask integer not null,
        granting boolean not null,
        audit_success boolean not null,
        audit_failure boolean not null,
        constraint unique_uk_4 unique(acl_object_identity,ace_order),
        constraint foreign_fk_4 foreign key(acl_object_identity) references acl_object_identity(id),
        constraint foreign_fk_5 foreign key(sid) references acl_sid(id)
);

I'm trying to create a new ACL.

var contact = new Contact();
contact.setName("John Doe");
contact.setId(1L);
var objectIdentity = new ObjectIdentityImpl(contact);

tt.execute(
    status -> {
      var acl = mutableAclService.createAcl(objectIdentity);
      var sid = new PrincipalSid("john");
      acl.insertAce(acl.getEntries().size(), BasePermission.READ, sid, true);
      mutableAclService.updateAcl(acl);
      return null;
    });

At first I thought it works but then I enabled logging for Spring Security.

logging.level.org.springframework.security=TRACE

Afterwards I started seeing the following error message.

I was confused because I use a Long identifier for my Contact entity and tried everything on my side but in the end never achieved to get rid of the error message.

To Reproduce

I spent quite some time to find a solution and I believe this is related to the following GitHub issues and Stack Overflow questions

• https://stackoverflow.com/questions/41706241/how-to-use-spring-security-acl-when-my-domain-identifiers-are-of-string-type
• ACL: acl_class class vs class_id_type for BasicLookupStrategy conflict #7598
• ACL module supports UUIDs as ObjectIdentity, documentation update needed #7978
• Object ID Identity conversion to long fails on old schema #7621

Expected behavior

We should not see any error messages in the logs.

Sample

Here is a minimal, reproducible sample https://github.com/zemirco/spring-security-acl.

Thank you! You're awesome and we love Spring Boot 🥳
