smbd start issue

In a configuration where the current LDAP server is decommissioned, but the mmuserauth was not changed to remove the service, smbd does not start because it cannot contact the decommissioned LDAP server. smbd only starts when it can reach the LDAP server. Authentication also cannot be removed because it requires a healthy samba.

To solve this issue, complete the following steps:
  1. Remove the LDAP configuration from the samba backend.
    /usr/lpp/mmfs/bin/net conf delparm global 'passdb backend'
  2. Start smbd.
  3. After samba is started, remove the authentication configuration and create authentication.
    # mmuserauth service remove
