Re: [nssldap] gentent works but "id" and "groups" commands fail with message "failed to get groups for user "

This may have been fixed in nss_ldap-260:

260     Luke Howard <lukeh@padl.com>

        * patch from Ralf Haferkamp <rhafer@suse.de>:
          only set errno for NSS_TRYAGAIN

I set up libnss-ldap on Linux to get user/group information

With getent it all looks fine to me, although I am not sure about
the password field (second field in getent passwd) which is 'x'
for local users and 'ABCD!efgh12345$67890' for ADS users.
Same with getent group, the group password field is 'x' for local
users and '*' for ADS users.

Even though getent output looks fine the
id and groups commands fail for users stored in ADS LDAP:


I ran into this problem with nss-ldapd. It may also affect nss_ldap (I
haven't looked at the code though that this is really the problem).

The GNU glibc docs [1] seem to suggest that if you return
NSS_STATUS_NOTFOUND you should set errno to ENOENT. This however causes 
problems with some tools.

Instead if get*ent() does not find any more entries it should just
return NSS_STATUS_NOTFOUND and not touch errno.
