October 2012 - sssd-users - Fedora Mailing-Lists

by Longina Przybyszewska

Hi list, I am going to set up proof-of -concept installation of Ubuntu (Precise) client/server using sssd to authenticate/authorize against Active Directory. At this moment everything seems to be a challenge - as I am exclusive (ok ;-) almost exclusive... ) hard core Linux user. As our Windows team is not ready with AD schema for Unix - my first exercise could be -get login/ssh authenticate (and change passwd) against AD -get uid/gid/auto.home map/shell from existing Linux NIS server Is my plan realistic ?

Re: [SSSD-users] sssd and different repositories

by Longina Przybyszewska

Ubuntu Precise has sssd-1.8.2 I use ' msktutil' - a very nice utility for joining AD domain. It is easy to join a bunch of computers and renew expired passwds with it. Realmd project looks interessant too. longina -----Original Message----- From: sssd-users-bounces(a)lists.fedorahosted.org [mailto:sssd-users-bounces@lists.fedorahosted.org] On Behalf Of Jakub Hrozek Sent: 16. oktober 2012 14:13 To: sssd-users(a)lists.fedorahosted.org Subject: Re: [SSSD-users] sssd and different repositories On Tue, Oct 16, 2012 at 10:21:02AM +0000, Longina Przybyszewska wrote: > Hi list, > I am going to set up proof-of -concept installation of Ubuntu > (Precise) client/server using sssd to authenticate/authorize against Active Directory. > At this moment everything seems to be a challenge - as I am exclusive (ok ;-) almost exclusive... ) hard core Linux user. > > As our Windows team is not ready with AD schema for Unix - my first > exercise could be -get login/ssh authenticate (and change passwd) > against AD -get uid/gid/auto.home map/shell from existing Linux NIS > server > > Is my plan realistic ? I'm not sure what version of the SSSD does Ubuntu Precise ship, but I would recommend using 1.9.x and the AD provider. You might also want to look into the realmd project, that could simplify joining an AD domain for you. _______________________________________________ sssd-users mailing list sssd-users(a)lists.fedorahosted.org https://lists.fedorahosted.org/mailman/listinfo/sssd-users

[SSSD] Announcing SSSD 1.9.1

This option is mainly useful for environments whose users come from a trusted domain so that the user doesn't have to specify that trusted domain with every user lookup. * Many man page fixes that were held from the 1.9.0 release during the string freeze * The entries in the generated known_hosts file are now expired preventing the file from growing indefinitely * The PID file is now created after all the SSSD services start up to avoid notifying the user via the init system before SSSD is able to handle requests. == Tickets Fixed == https://fedorahosted.org/sssd/ticket/1303 SSSD is slow at startup https://fedorahosted.org/sssd/ticket/1357 Init script reports complete before sssd is actually working https://fedorahosted.org/sssd/ticket/1471 Range Retrieval: Unable to retrieve all members when filter is used in search base. https://fedorahosted.org/sssd/ticket/1483 Mention ldap_schema types on newlines or comma separate them. https://fedorahosted.org/sssd/ticket/1494 ldap_chpass_update_last_change is not included in the manual page https://fedorahosted.org/sssd/ticket/1525 Explain default re_expression in IPA and AD provider man pages https://fedorahosted.org/sssd/ticket/1529 [RFE] Login with users from a trusted domain always requires a FQ name https://fedorahosted.org/sssd/ticket/1533 Improve recreating new ccache file when the old one is not accessible any more https://fedorahosted.org/sssd/ticket/1535 Flip the default value of ldap_initgroups_use_matching_rule_in_chain https://fedorahosted.org/sssd/ticket/1537 Fix sssd-ad id ranges https://fedorahosted.org/sssd/ticket/1540 [man sssd-ldap] 'ldap_access_filter' description needs to be updated https://fedorahosted.org/sssd/ticket/1541 Manpage has ldap_autofs_search_base as experimental feature https://fedorahosted.org/sssd/ticket/1542 User authentication using LDAP doesn't work https://fedorahosted.org/sssd/ticket/1546 sss_seed "-h" and "--help" options should output similar results https://fedorahosted.org/sssd/ticket/1548 User authentication fails when password is read from a file using -p option of SSS_SEED tool. https://fedorahosted.org/sssd/ticket/1549 Providing invalid UID/GID values, terminates sss_seed tool without any error message https://fedorahosted.org/sssd/ticket/1554 sss_seed should not allow blank passwords https://fedorahosted.org/sssd/ticket/1562 Domains overlap in range 1 - 4294967295 https://fedorahosted.org/sssd/ticket/1563 Document the need to restart autofs service. == Detailed Changelog == Jakub Hrozek (11): * Bumping the version to 1.9.1 release * Document ldap_chpass_update_last_change * sudo and autofs search bases should not be marked experimental * Flip the default value of ldap_initgroups_use_matching_rule_in_chain * Include param_help_py.xml in the list of po4a sources * Note that Range Retrieval is not supported when filter is used in the search base. * Change the log level of two DEBUG messages in check_domain_ranges * Remove unused variable * Check for existing pidfile before starting the providers * man: Note that automounter must be restarted to re-read the master map * Updating the translations for 1.9.1 release Jan Cholasta (2): * SSH: Refactor sysdb and related code * SSH: Expire hosts in known_hosts Michal Zidek (7): * Change option to display help message in man pages. * sss_seed: Option --debug did not work in sss_seed tool. * sss_seed: Show error message when interactive input fails. * sss_seed: Make only first line of password file valid. * sss_seed: Passwords longer then PASS_MAX not allowed. * sss_seed: Improved error message when the domain does not exist. * Variable in sdap_sudo_rules_refresh_send could be used, uninitialized.
