group_user_ensure fails in suse 11 sp3

[Roger]

Hi Sebastian please check this

group_user_ensure(group='test', user='www')

I got this:

sudo: usermod -a -G 'test' 'www'
[mo9e] out: usermod: invalid option -- 'a'
[mo9e] out: Try `usermod --help' or `usermod --usage' for more information.
[mo9e] out:


Fatal error: sudo() received nonzero return code 2 while executing!

Requested: usermod -a -G 'test' 'www'
Executed: sudo -S -p 'sudo password:'  /bin/bash -l -c "usermod -a -G 'test' 'www'"

As per the man doesn't exist an option "-a"

SUSE's usermod is not the same as the one on Debian/Ubuntu. The one shipped here is from shadow-utils 4.1.5.1. Could you paste me the output of cat /etc/lsb-release on your remote system?

[Roger]

There is the output:

~> cat /etc/*release*
SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 3
LSB_VERSION="core-2.0-noarch:core-3.2-noarch:core-4.0-noarch:core-2.0-x86_64:core-3.2-x86_64:core-4.0-x86_64"

[Sébastien Pierre]

Not sure I want to add a specific case to handle that, I don't see a combination of options that would work for both usermod commands. Do you have shadowutils installed?

[Roger]

no, I have pwdutils

# rpm -qf /usr/sbin/usermod
pwdutils-3.2.15-0.13.1

You're welcome to create a pull request for that, as I don't have the environment at hand to test it -- this could be defined as a variant (such as what we already do with the package_* functions).
