backend not loading because of mistyped filename "libsss_krb5 .so"

[Alexander Fieroch]

We are running a domain with ldap as id_provider and kerberos as auth_provider. The backend is not loading in ubuntu 13.10. Ubuntu 13.04 was working with the same configuration.

In /etc/sssd/sssd_DOMAIN.log I find following error:

[load_backend_module] (0x0010): Unable to load krb5 module with path (/usr/lib/x86_64-linux-gnu/sssd/libsss_krb5 .so), error: /usr/lib/x86_64-linux-gnu/sssd/libsss_krb5 .so: cannot open shared object file: No such file or directory

There is a space character in the filename libsss_krb5.so and that's why the module is not loading. The file /usr/lib/x86_64-linux-gnu/sssd/libsss_krb5.so without the space character does exist.

Please fix it! It blocks connecting to our domin with ubuntu 13.10. Thanks!

it's a typo in your sssd.conf, check that there is no trailing whitespace in it

[Jakub Hrozek (jakub-hrozek)]

Timo, libini (a component of ding-libs) should be stripping the trailing whitespace. This was a known upstream bug fixed in 7a2eb259b2e22ce5e2395fbf578b5fef57667489 in ding-libs.

There is a number of pending patches upstream, when those are reviewed, a new ding-libs release will be done.

Sorry for the inconvenience.

[Timo Aaltonen (tjaalton)]

right, that's what it was.. moving to ding-libs then

[Alexander Fieroch (fieroch)]

sounds good but I do not find any trailing whitespaces in each configuration line in my sssd.conf.
Which corresponding option is used to build the mistyped filepath "/usr/lib/x86_64-linux-gnu/sssd/libsss_krb5 .so"?

[Alexander Fieroch (fieroch)]

I found the corresponding option 'auth_provider=krb5' but there is NO whitespace! There has to be a bug in libini.

Setting 'auth_provider="krb5"' would search for /usr/lib/x86_64-linux-gnu/sssd/libsss_"krb5".so without a whitespace. Removing the quotation marks and to be sure there is no whitespace again searches for /usr/lib/x86_64-linux-gnu/sssd/libsss_krb5 .so with a whitespace.

I'm running Kubuntu 13.10 with

# dpkg -l | grep libini
ii libini-config3:amd64 0.3.0.1-1 amd64 INI file parser for C

[Timo Aaltonen (tjaalton)]

check the next line too..

This bug was fixed in the package ding-libs - 0.3.0.1-2

Hm, I upgraded to ding-libs - 0.3.0.1-2 but it still doesn't work.
After commenting out every blank line in sssd.conf it works! There is still a problem with blank lines in 0.3.0.1-2.
