udev ldap wait

udev ldap wait

[Jan Engelhardt]

Hi,


ttyS0 picked this up on boot.

                Welcome to Aurora SPARC Linux
                Press 'I' to enter interactive startup.
Setting clock  (localtime): Sat Aug 25 15:21:39 CEST 2007 [  OK  ]
Starting udev: udevd[370]: nss_ldap: failed to bind to LDAP server ldar
udevd[370]: nss_ldap: failed to bind to LDAP server ldap://127.000.1: Can't conr
udevd[370]: nss_ldap: reconnecting to LDAP server (sleeping 4 seconds)...

Well, that happens if you have 'bind_policy hard_open' in 
/etc/ldap.conf. Looks like a bad idea, I admit. But does udev really 
need to getpwfoo()?

Make sure, that all the system users and groups, used in udev rules,
exist in the local database, and that the local files are used before
you lookup any other directory service. It will not even try to use
the network, just like /etc/hosts can prevent dns lookups. System
users and groups should exist on the local machine for various
reasons, it's not only udev that has problems with it.

That is guaranteed. The LDAP slave just carries the users with portable UIDs,
which, as it stands, is limited to accounts for real-world people.

That is set too in nsswitch.conf ("passwd: files ldap")

Still it does trigger nss_ldap. I have now forced 'bind_policy soft' (also a
SUSE default), and I can ignore the warnings.

Hmm, there must be an entry in a rules file, that doesn't exist in the
local db.

On the running system, can you put an invalid ldap IP addess in the
config, or disconnect the box from the network and do:
  $ killall udevd
  $ killall nscd
  $ udevd -v

It shows here (after a long timeout):
  udevd -v
  [9575] parse_file: reading '/etc/udev/rules.d/05-udev-early.rules' as rules file
  [9575] parse_file: reading '/etc/udev/rules.d/10-local.rules' as rules file
  [9575] lookup_group: error resolving group 'does-not-exist': Connection timed out
  [9575] parse_file: reading '/etc/udev/rules.d/40-alsa.rules' as rules file
  ...
