Kerberos delegation

Hi everyone

 

I need to configure kerberos delegation I am following the instructions from this link http://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm_implementations_guide_10_1/sol_kerberos_delegation.html

 

I get error messages when I want to join the BIG-IP system to the trusted domain

 

When I run

 

domaintool --add --kdc I get no error and when I run domaintool --list

 

I can see the domain name

 

But for domaintool --join --admin_principal --host it does not work it prompts me for the password (I tried with 2 administrative accounts) I enter the password but I get the following errors Error: ldap_sasl_interactive_bind failed(Local error) Error: ldap_connect failed Couldn't join domain(65280). at /usr/bin/domaintool line 387, line 32.

 

What am I missing

 

Thanks

 

Michel
