In TID (3003589) :

Reconfigure Linux User Management

1. Launch YaST
2. Go to Security and Users
3. Choose the Linux User Management module
4. Reconfigure according to your environment
5.
* Use this YaST module rather than iManager to reconfigure
* Make sure the LDAP ports are 389 and 636

I simply can NOT Linux User Management module in that place

How do I re-configure LUM

Thanks

Seb
