APM Kerberos AUTH with strong encryption algorithm (AES) support.

Hello,

 

Tell me please which version of BIGIP support AES256 in keytab for Kerb Auth?

 

In my Enviroment (Win2012+BIGIPv13) I can use only rc4-arcfour-hmac in keytab (as described in manual https://support.f5.com/kb/en-us/products/big-ip_apm/manuals/product/apm-authentication-single-sign-on-11-5-0/9.html). But, if I generate a key with the AES256 encryption, then the authentication does not work and the following errors occur:

 

**...modules/Authentication/Kerberos/KerberosAuthModule.cpp: 'display_status_1()': 94: 7bc9dd3a : GSS-API error gss_accept_sec_context: d0000 : Unspecified GSS failure. Minor code may provide more information ...modules/Authentication/Kerberos/KerberosAuthModule.cpp: 'display_status_1()': 94: 7bc9dd3a : GSS-API error gss_accept_sec_context: 186a5 :**

As I understand, changing the config (/etc/krb5.conf) manually is not supported (as each APM Policy update or restart apmd service overwrites the config).
