UserNameAttribute "uid" not existing in objectClass "inetOrgPerson"

[Al2Klimov]

Describe the bug

When configuring an LDAP user backend in Icinga Web 2, the validation process fails due to the uid attribute not being recognized as part of the inetOrgPerson object class.

To Reproduce

1. Create a resource exactly as below
2. Attempt to create an LDAP user backend from it, validate configuration
3. Failed to successfully validate the configuration: UserNameAttribute "uid" not existing in objectClass "inetOrgPerson"
4. Add LDAP Filter (uid=*), validate configuration
5. The configuration has been successfully validated. (...) 14 users found in backend

Resource

[forumsys]
type = "ldap"
hostname = "ldap.forumsys.com"
port = "389"
encryption = "none"
root_dn = "dc=example,dc=com"
bind_dn = "cn=read-only-admin,dc=example,dc=com"
bind_pw = "password"
timeout = "5"

Expected behavior

Icinga Web auto-adds (LDAP User Name Attribute=*) to filter.
