Re: [augeas-devel] possible bug with krb5.conf lense



Hi Dominic,

Thanks for the info.

I didn't realise that the EPEL version of augeas for EL5 is 1.1.0, but RHEL6 ships with 0.9.x, hence no package in EPEL for EL6.
It's a pity there aren't updated augeas packages for EL6 in EPEL, but I guess that breaks the EPEL philosophy.

I'll look for another source for the rpm.

Thanks

J

It seems to have been fixed between 0.9.0 and the current release, 1.1.0.  I can reproduce it on the former, but not the latter:

augtool> set /augeas/context /files/etc/krb5.conf set 
augtool> appdefaults/forwardable true set appdefaults/application pam 
augtool> set appdefaults/application/debug false save
Saved 1 file(s)
augtool> ^Z
[1]+  Stopped                 augtool -r /tmp/k5
$ cat /tmp/k5/etc/krb5.conf

[appdefaults]
forwardable = true
pam = {
debug = false
}

The syntax looks correct now.
