Find krb5 path is failed

[stanislavlevin]

Hello!

Search for a krb5 plugin's dir is failed due permissions denied (even the path is right).

ERROR: Failure: AttributeError ('NoneType' object has no attribute 'endswith')

There is a small patch to fix it.

Thank you.

Hi, thanks for the issue and the patch!

In general there are more flags to find being passed than I would expect. Is there something I'm missing that would cause find %s/ -type d ! -executable -o -path "*/krb5/plugins" to not work?

[stanislavlevin]

First, find should prune not executable and not readable paths. As you suggest:

find /usr/lib/ -type d ! -executable -o -path "*/krb5/plugins";echo $?
/usr/lib/screen
find: ‘/usr/lib/screen’: Отказано в доступе
/usr/lib/chkpwd
find: ‘/usr/lib/chkpwd’: Отказано в доступе
/usr/lib/utempter
find: ‘/usr/lib/utempter’: Отказано в доступе
/usr/lib/consolehelper/priv
find: ‘/usr/lib/consolehelper/priv’: Отказано в доступе
/usr/lib/alterator/hooks
find: ‘/usr/lib/alterator/hooks’: Отказано в доступе
/usr/lib/krb5/plugins
find: ‘/usr/lib/openssh’: Отказано в доступе
1

Excuse me for Russian(it means permission denied).
Please look at the below command:

find /usr/lib/ -type d \( ! -executable -o ! -readable \) -prune -o -type d -path "*/krb5/plugins" -print; echo $?
/usr/lib/krb5/plugins
0

Thank you.

that makes sense, LGTM 👍 Thanks! I'll merge it.
