[Freeipa-users] ipa-adtrust-install fails with invalid 'cn': must be Unicode text

[iulian roman]

Hello, 

When I run ipa-adtrust-install command in order to configure trust prerequisites , it
fails in step 4, with the following error: 

Configuring CIFS
  [1/24]: validate server hostname
  [2/24]: stopping smbd
  [3/24]: creating samba domain object
Samba domain object already exists
  [4/24]: retrieve local idmap range
  [error] ConversionError: invalid 'cn': must be Unicode text
Unexpected error - see /var/log/ipaserver-install.log for details:
ConversionError: invalid 'cn': must be Unicode text

The existing idrange is in the following format :
dn: cn=IPA.EXAMPLE.COM_id_range,cn=ranges,cn=etc,dc=ipa,dc=example,dc=com


Any hint/suggestion would be really appreciated .
