Cannot authenticate users in different OUs against parent DN

[lofidevops]

Steps to reproduce:

1. Create the following DNs in an OpenLDAP directory:

   • DN: uid=usera,ou=sub1,dc=example,dc=com
   • DN: uid=userb,ou=sub2,dc=example,dc=com

2. Set the following Simple LDAP Login settings:

   • Base DN: dc=example,dc=com
   • Search Sub OUs: Yes

3. Attempt to log in as usera, then as userb

What should happen:

Login is successful for both users.

What happens instead:

Login fails for both users.

Notes:

• If I set "Base DN" to "ou=sub1,dc=example,dc=com", then usera can log in.
• If I set it to "ou=sub2...", then userb can log in.
