After performing a recent update (emerge -uDN world), which had not been done for a couple of months, I tried to emerge a new package and the emerge fails to even start properly, I tried emerging different packages and all do the same for example: emerge gaim Calculating dependencies ... done! >>> Emerging (1 of 1) net-im/gaim-1.5.0 to / And thats all I get, I tried emerge-webrsync and that didn't help either. Eventually I discovered that if I swap the order in my nsswitch.conf from ldap files to files ldap emerge worked. Now I have a new problem that su no longer works it always says su - Password: su: Permission denied Sorry. There is one way round this and that is to add the user to /etc/group and /etc/password, but that defeats the object of LDAP! Reproducible: Always Steps to Reproduce: 1.using a working system implement ldap (LDAP server has account details of all local system accounts) 2.modify the lines in /etc/nsswitch.conf to change the following lines to read passwd: ldap files group: ldap files this causes portage to fail the emerge. 3.try to emerge something and watch it fail 4. Modify nsswitch.conf to read passwd: files ldap group: files ldap 5. Now try and su to root Actual Results: Step 3. emerge gaim Calculating dependencies ... done! >>> Emerging (1 of 1) net-im/gaim-1.5.0 to / can su to root successfully Step 5. su - Password: su: Permission denied Sorry. other apps also fail such as cxoffice emerge now works successfully Expected Results: expect both emerge, and su and cxoffice to work regardless of the order in nsswitch.conf adding the user to /etc/group and /etc/passwd is a short term workaround to allow su and cxoffice apps to work but implementing the changes on every machine makes a mockery of the ldap implementation.

sys-auth/nss_ldap-253
I'm not sure this is an ldap bug, what I think is happening is that some applications are only looking in one of the options in /etc/nsswitch.conf and then ignoring the second option. I think this because switching files and ldaps order in the nsswitch.conf fixes the issue for one application, however it breaks it for another.
I can't restart services (apache etc) when the nsswitch.conf is in the order ldap files
files must ALWAYS come before ldap in any nsswitch.conf line, otherwise there is a lot more nasty stuff that will happen when you boot your machine. As for su being broken, what authentication is su using? It should using pam_ldap, so please validate that.
portage.doebuild returns 3328 in the emerge script line 2030, when /etc/nsswitch.conf's order is ldap files.

This has been working fine until I updated my machine so I don't think I have any issues there. pam_ldap su uses #%PAM-1.0 auth sufficient pam_rootok.so # If you want to restrict users begin allowed to su even more, # create /etc/security/suauth.allow (or to that matter) that is only # writable by root, and add users that are allowed to su to that # file, one per line. #auth required pam_listfile.so item=ruser sense=allow onerr=fail file=/etc/security/suauth.allow # Uncomment this to allow users in the wheel group to su without # entering a passwd. #auth sufficient pam_wheel.so use_uid trust # Alternatively to above, you can implement a list of users that do # not need to supply a passwd with a list. #auth sufficient pam_listfile.so item=ruser sense=allow onerr=fail file=/etc/security/suauth.nopass # Comment this to allow any user, even those not in the 'wheel' # group to su auth required pam_wheel.so use_uid auth include system-auth account include system-auth password include system-auth session include system-auth session required pam_env.so session optional pam_xauth.so system-auth contains: auth required pam_env.so auth sufficient pam_unix.so likeauth nullok shadow auth sufficient pam_ldap.so use_first_pass auth required pam_deny.so account requisite pam_unix.so account sufficient pam_localuser.so account sufficient pam_ldap.so account required pam_unix.so password required pam_cracklib.so difok=2 minlen=8 dcredit=2 ocredit=2 retry=3 password sufficient pam_unix.so nullok md5 shadow use_authtok password sufficient pam_ldap.so use_authtok use_first_pass password required pam_deny.so session required pam_limits.so session required pam_unix.so session required pam_mkhomedir.so skel=/etc/skel/ umask=0066 session optional pam_ldap.so As said in my first post this all works fine if the order is ldap files, however other things are now broken that were previously working fine.
Could this issue related to bug 147625 ? The issue is that portage always return error 3328 when using ldap storage based accounts. So, the real bug is in glibc and the way it handle maps and usernames, see bug 156511. From my personal experience, if you have TLS or SSL enabled in /etc/ldap.conf, tunring it off makes things working.
This looks like bug 162355, which corresponds to the upstream bug http://bugzilla.padl.com/show_bug.cgi?id=273 (nice description there). Using nscd should probably solve the issue.
257 in CVS now with the SIGPIPE fix, closing.
