KB-1516: adjoin -k fails to join a domain whose domain and forest functional levels are Windows Server 2008

Centrify DirectAudit ,   Centrify DirectControl ,   Centrify Identity Service, Mac Edition ,  

12 April,16 at 11:45 AM

Applies to: All versions of Centrify DirectControl for UNIX/Linux

 

Problem:

 

adjoin with option "-k" fails to join a domain whose domain and forest functional levels are Windows Server 2008. Running it yields the following error message:

 

bash-3.00# adjoin -p pass,123 -k server.test
Using writable domain controller: win-nqe8dmvosvd.server.test
Error: Invalid user or password

Join to domain 'server.test', zone 'default' failed.

 

Cause:

 

[root@rhel3 root]# adjoin --help | grep des
  -k, --des                use DES key only

 

-k means to use DES encryption during the adjoin operation; DES encryption is no longer supported by Windows 2008 domains by default.

 

Resolution:

 

One can manually enable DES on the domain by setting the following group policy:

 

Under Computer Configuration/Windows Settings/Local Policies/Security Options/Network Security:

i. Configure available encryption types for Kerberos
ii. Enable All but "Future Encryption Types"
iii. Reboot Domain Controller.
