Hi,

I am having problems configuring Solaris 10 client to work with FreeIPA
v2 server. Everything seems to be working fine except for password
change. When I try to change the password I get this error:

$ kpasswd
kpasswd: Changing password for u...@example.com.
Old password:
kpasswd: Cannot establish a session with the Kerberos administrative
server for realm EXAMPLE.COM. Database error! Required KADM5 principal
missing.

In KDC log I can see this entry:

AS_REQ (6 etypes {18 17 16 23 3 1}) 10.134.19.22: SERVER_NOT_FOUND:
u...@example.com for changepw/freeipa.example....@example.com, Server
not found in Kerberos database

(freeipa.example.com is my FreeIPA server)

And this is how it looks like when it's working:

AS_REQ (2 etypes {3 1}) 192.101.1.73: NEEDED_PREAUTH: u...@example.com
for kadmin/chang...@example.com, Additional pre-authentication required

It seems that Solaris is requiring
changepw/freeipa.example....@example.com Kerberos principal for password
changes, instead of kadmin/chang...@example.com. I have a landscape with
AIX, HP-UX, Linux and Solaris servers, and all other systems do not use
mentioned principal, so this seems to be something specific to Solaris
(or maybe specific to my configuration :)).

Is there a way to instruct Kerberos client which principal to use for
password changes? Or, if not, how to add the missing principal (I do not
see a way of doing it with FreeIPA commands)?

Installed software:

Client:
SUNWkrbr/SUNWkrbu 11.10.0,REV=2005.01.21.16.34

Server:
389-ds-base-1.2.6.1-2.fc13.i686

python-iniparse-0.4-1.fc13.noarch
python-krbV-1.0.90-1.fc13.i686

Thanks,
Miljan

The good news is that I can reproduce this on my Solaris 10 system. The bad news is I'm not sure what the solution is yet. I'll keep looking.
