Re: Configuration of idmap_ldap "No backend defined"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi,

please check your ldap configuration in your smb.conf file. At first verify that your base-dn is really  "dc=example,dc=com". Than remove "cn=Manager" from each option that contains "base_dn".

As usual, make sure that your LDAP server is set up correctly and that everthing works fine. Than you can connect samba to your LDAP. 

Cheers,

Christian
