LDAP Server, Healthy but not users and Cache Rebuild timimg out

Hi, I just installed a fresh openldap server with rcdevs sldap Directory. It is working in opnsense correctly.
But in Truenas I configured baseDN and BindDN correctly with port 389. It appeared healthy but there are no user provides in Truenas Usermanagement.
After pressing Rebuild cache I got a timeout.
[EFAULT] Timed out while waiting for domain to come online
Structure is really simple:
cn=user1,ou=users,o=Root
ldif export has all objectclasses truenas should need:
dn: cn=user1,ou=users,o=Root
objectclass: webadmaccount
objectclass: person
objectclass: inetorgperson
objectclass: posixaccount
objectclass: organizationalperson
objectclass: sambaconfig
objectclass: top
uid: user1
sn: 1
preferredlanguage: DE
c: DE
givenname: user
cn: user1
uidnumber: 500
gidnumber: 100
homedirectory: /home/user1
loginshell: /bin/bash
userpassword: {SSHA}J3+d

Can someone give me a hint… me and chatgpt has no other idea :wink:

mhh noboday? Did you need more information from me? Will share what I can. I can not be the only one using ldap and have trouble with that… ok maybe I am to stupid, but then… tell me :wink:

It looks like you’re assigning UID / GID numbers below 1000 in your LDAP. SSSD won’t detect anything that low. Best-practice in general is to reserve low IDs for local system accounts. Honestly, you’re better off going much higher to avoid conflict with local accounts on systems (maybe start at 100K or one million).
