[Bug 567188] Re: krb5 and ADS error using 10.04, not 9.04

[Jean-Baptiste Lallement]

Jean-Yves, did you tried the advice from Sam Hartman in comment #12 ?
Is is still an issue with Ubuntu 10.10 - Maverick ?
Was it an issue in Ubuntu 9.10 ?

** Also affects: krb5 (Ubuntu Lucid)
   Importance: Undecided
       Status: New

** Tags added: regression-release
** Tags removed: regression-potential

** Changed in: krb5 (Ubuntu Lucid)
       Status: New => Confirmed

** Changed in: krb5 (Ubuntu Lucid)
   Importance: Undecided => Medium

** Description changed:

  Environment:
  The installed distributions use kerberos and likewise to identify the user to an Active Directory Server.
  The client configuration on 9.04 is basic and efficient. I use the same configuration file (krb5.conf) on 10.04.
  Kerberos and likewise come from ubuntu repository for each distribution (9.04 and 10.04).
  
  Description:
  Using 9.04 to auth with kerberos/likewise works fine: tickets ok, everything is done login in one time only.
  Using 10.04 to auth the same way leads to an error and forbids the access: user login ok but the access to other ressources is forbidden, most often returning: KRB Error: KRB5KDC_ERR_S_PRINCIPAL_UNKNOWN.
  The likewise-open5 versions used are the same on both distributions.
  I tested with same versions of kerberos on both distributions and i got the same results.
- I thought the "KRB5KDC_ERR_S_PRINCIPAL_UNKNOWN" was related to a dns problem but when i solved this the following appears: 
-      the client sends a TGS_REQ, containing the "Encryption type: rc4-hmac (23)", to the server.
-      the server answers "KRB5KDC_ERR_ETYPE_NOSUPP (14)"
-      10.04 sends a section "Authenticator rc4-hmac (23)" in PA-TGS-REQ , 9.04 doesn't.

  There's no such error using ubuntu-9.04.
  I grab theses informations sniffing the local network with wireshark.
  
  Is there anybody experiencing the same problems ?
  How can i fix this ?
  thanx
