* Make password expiry messages correct and consistentArthur de Jong2018-08-062-14/+14
| | | | | Thanks to Têko Mihinto. See https://bugzilla.redhat.com/show_bug.cgi?id=1612543
* Add domain variable for use in pam_authz_searchArthur de Jong2018-07-212-2/+7
| | | | | | | | | This adds a domain variable (if it can be determined on the system) that can be used in pam_authz_search and pam_authc_search filters to build search filters that search on the domain name (the FQDN without the starting host name). Closes https://github.com/arthurdejong/nss-pam-ldapd/issues/8
* Allow logging longer linesArthur de Jong2018-07-211-1/+1
| | | | | | | This increases the buffer that holds log messages so longer messages can be logged. Closes https://github.com/arthurdejong/nss-pam-ldapd/issues/26
* Create /var/run/nslcd/socket after dropping privilegesArthur de Jong2018-07-211-3/+3
| | | | | | | | | | This is needed to avoid a problem where a call to initgroups() can result in NSS lookups. If nscd is configured the mechanism to avoid loopback lookups using nss_ldap_enablelookups will not work and cause for delays on start-up. Note that this changes ownership of the socket to the user running nslcd.
* Increase size of hostname bufferArthur de Jong2018-02-172-13/+4
| | | | | | | | This increases the host name buffer to support host names (that include FQDNs) to 255 characters and removes the reliance on HOST_NAME_MAX and _POSIX_HOST_NAME_MAX which may be smaller in some situations. Closes https://github.com/arthurdejong/nss-pam-ldapd/issues/22
* Increase size of config file tokenArthur de Jong2017-12-231-1/+1
| | | | | | | | This increases the maximum size of tokens that are read from the nslcd.conf configuration file to 256 characters. This was a problem for some very long uri values. Closes https://github.com/arthurdejong/nss-pam-ldapd/issues/21
* Support spaces in attribute mapping expressionsArthur de Jong2017-10-131-5/+4
|
* Get files ready for 0.9.8 release0.9.8Arthur de Jong2017-06-261-2/+2
|
* Add the ability to offset UID and GID numbersSeth Wright2017-06-204-0/+21
|
* Use uint8_t instead of u_int8_tArthur de Jong2017-06-181-4/+4
| | | | | | The former seems to be available on more platforms than the latter. Fixes be26510.
* Also filter shadow entries by validnamesArthur de Jong2017-06-181-11/+24
|
* Fix and clarify a few commentsArthur de Jong2017-06-182-3/+3
|
* Allow skipping post-authentication search altogetherArthur de Jong2017-06-151-1/+1
|
* Implement myldap_bind() functionArthur de Jong2017-06-154-103/+84
| | | | | | | | | | | | | This function integrates the myldap_set_credentials() and myldap_get_policy_response() and performs the bind operation witout actually performing a search. The function performs a "fake" search that returns after performing the LDAP BIND operation. This replaces a number of dummy search operations that were there to ensure that the connection was open. This allows us to skip the search operation after authentication.
* Implement handling of pam_authc_search optionArthur de Jong2017-06-151-13/+42
| | | | | This allows performing a different, configurable search from the default BASE search after the BIND operation.
* Add pam_authc_search option parsingArthur de Jong2017-06-153-21/+48
|
* Reorganise PAM search var building functionsArthur de Jong2017-06-141-118/+133
| | | | | | | | | | This moves the autzsearch_var_add(), autzsearch_vars_free(), autzsearch_var_get() and do_autzsearches() functions to the top of the file using more generic names and introduces search_vars_new() in prepartion of other similar searches. This also renames the remaining authzsearch functions to authz_search to be consistent with the pam_authz_search option.
* Query ethernet addresses in compact and long formatArthur de Jong2017-06-131-10/+22
| | | | | | | | | | | This ensures that when querying the address 0:18:8a:54:1a:8b both that format and 00:18:8a:54:1a:8b is searched for in LDAP. This was triggerred by the fact that ether_ntoa() on FreeBSD returns the long format while glibc uses the compact format. Since we are no longer using the libc version of ether_ntoa() we can also drop the compatibility implementation of ether_ntoa_r().
* Log entries and lookups failing nss_min_uidArthur de Jong2017-06-071-2/+15
| | | | | | This logs (at debug level) any LDAP uidNumber attribute values (or translated objectSid attribute values) that are lower than nss_min_uid. It also logs getpwuid() requests for such uids.
* Exit with 0 when stopping nslcdArthur de Jong2017-02-071-1/+1
| | | | | | | When receiving a signal this will result in nslcd returning with a success exit code. Thanks Stanislav Moravec for pointing this out.
* Remove duplicate break statementArthur de Jong2016-09-041-1/+1
|
* Do not try all LDAP servers on failed authenticationArthur de Jong2016-09-041-0/+7
| | | | See https://bugs.launchpad.net/bugs/1618190
* Get files ready for 0.9.7 release0.9.7Arthur de Jong2016-08-141-2/+2
|
* Also honor ignorecase in PAMArthur de Jong2016-06-031-1/+1
| | | | | | | This avoids changing the cannonical username to the value as specified in LDAP when ignorecase is used. See https://github.com/arthurdejong/nss-pam-ldapd/issues/12
* Display human readable expiry messageMathieu Baeumler2016-02-131-8/+59
| | | | | Display a human readable message (days+hours, or hours+minutes, or seconds) when the password expiring warning is issued.
* Fix nss_disable_enumeration configurationArthur de Jong2016-02-131-1/+1
| | | | | | | This fixes a copy-paste bug where nss_disable_enumeration was incorrectly handled. Fixes c0366d8. Thanks Andrew W Elble for pointing this out.
* Add pam_authc_ppolicy optionMathieu Baeumler2016-01-063-19/+49
| | | | This option allows completely disabling ppolicy handling.
* Fix error handling on credential changeArthur de Jong2016-01-061-2/+4
| | | | | This fixes setting the correct LDAP error code and also fixes formatting in 027df03.
* Fix updating of 'shadowLastChange' attribute when ↵Vasilis Tsiligiannis2015-12-231-0/+9
| | | | | | | | | | chasing referrals This fixes a bug where 'shadowLastChange' attribute cannot be updated when chasing a referral. After a password is succesfully changed, the credentials for binding should also be updated with the new password for the session. Signed-off-by: Vasilis Tsiligiannis <vasilis.tsiligiannis@nokia.com>
* Correct file readability checkArthur de Jong2015-11-131-9/+2
| | | | | This uses access() instead of stat() to see if the file is readable by the current process. This fixes f089e01.
* Fail-over and retry on more errorsArthur de Jong2015-09-301-1/+4
| | | | | | Also try to fail over to another LDAP server on a larger number of errors. Specifically errors that point to problems connecting to the LDAP server.
* Open connection before do_try_search()Arthur de Jong2015-09-301-5/+5
| | | | | This is in preparation for splitting the BIND from the search phase for authentication.
* Loosen up file existence checkArthur de Jong2015-08-271-70/+65
| | | | | | | | | | | | | This changes the check (for configuration options that specify file names) to just check that the specified path is readable instead of ensisting that it points to a file. This allows tls_randfile to point to /dev/urandom (a character device) or a pipe. This fixes 6779a51. This also applies the same check to the krb5_ccname option. Thanks to Patrick McLean for pointing this out.
* Simplify password policy message handlingArthur de Jong2015-08-151-14/+20
| | | | | | | | | | | This simplifies the check for overwriging pending password expiry and grace logins warnigns and updates handling of the LDAP_CONTROL_PWEXPIRING control to be consistent with that of the expire value of LDAP_CONTROL_PASSWORDPOLICYRESPONSE. This also corrects the function name, also logs empty password policy responses in debug mode and documents the meaning of the various password policy values.
* Fix password policy expiration warningsMathieu Baeumler2015-08-151-3/+1
| | | | | | | | | | If a password expiration warning (pwdExpireWarning) is set in slapd, and the password is about to expire, slapd sends the timeBeforeExpiration value as part of the passwordPolicyResponse. nslcd would incorrectly instruct the PAM module to require immediate password change. This has been fixed for both timeBeforeExpiration and graceLoginsRemaining.
* Check file existence for configuration optionsArthur de Jong2015-07-191-5/+43
| | | | | | This adds addition checks to the tls_cacertdir, tls_cacertfile, tls_randfile, tls_cert and tls_key options to ensure that they point to an existing file when parsing nslcd.conf.
* Also fix signed integer bug in binsid2id()Arthur de Jong2015-06-132-2/+2
| | | This should have been part of d217632.
* Fixed signed 32bit overflow bug on 32bit systemsGeoffrey McRae2015-06-111-14/+18
|
* Allow configuration values longer than 63 charactersJed Liu2015-05-241-2/+2
|
* Implement disable_enumerationAndrew Elble2015-05-013-3/+17
| | | | | | | | | | If this option is present, functions which cause all user/group entries to be loaded (getpwent(), getgrent()) from the directory will not succeed in doing so. This can dramatically reduce ldap server load in situations where there are a great number of users and/or groups. Applications that depend on being able to sequentially read all users and/or groups may fail to operate correctly. This option is not recommended for most configurations.
* Implement nss_getgrent_skipmembersArthur de Jong2015-04-203-5/+16
| | | | | | | This option allows skipping group member list retrieval to improve performance with very large groups. This option results in inconsistent group membership information being presented that may confuse some applications.
* Avoid signal race condition on start-upArthur de Jong2015-04-162-3/+4
| | | | | | | This only restores the signal mask after signal handlers are in place and the daemon has completely daemonised to avoid a race condition in the start-up phase of nslcd where a signal could be sent to nslcd causing it to quit or fail to write information to the parent process.
* ENODATA is missing on FreeBSDArthur de Jong2015-03-221-1/+5
| | | | FreeBSD doesn't have ENODATA so we use ENOATTR instead.
* Various small fixes when using --with-module-nameArthur de Jong2015-03-222-4/+4
| | | | | | | This updates the test framework to support --with-module-name, ensures that exports.map is rebuilt when configure is re-ran, fixes parsing of nsswitch.conf (to determine what to return for passwd lookups) and fixes the check for _nss_ldap_version.
* Fix formatting of size_t valuesPatrick McLean2015-03-143-12/+12
| | | | | | | | In several places the code used a %d format to print a size_t variable. On amd64 at least size_t is an unsigned long, so use %lu instead. An alternative would be to use %ud for size_t and %zd fo ssize_t but not all platforms seem to support that formatter.
* Avoid comparison of static array to null pointerPatrick McLean2015-03-111-4/+4
| | | | | | | There are several places where a static length array in a struct is compared to a null pointer. These comparisons will always be false, since an array in a struct is not actually a pointer, so they can be removed.
* Don't let the oom killer kill nslcdPatrick McLean2015-03-111-0/+23
| | | | | Adjust the Linux OOM (Out-Of-Memory) killer score by -1000 for nslcd so that it should not be killed.
* Allow configuration of NSS and PAM namesArthur de Jong2015-01-191-3/+3
| | | | This introduces the --with-module-name configure option to allow building of NSS and PAM modules with different namespaces than ldap.
* Avoid accessing searches outside arrayArthur de Jong2015-01-191-1/+1
| | | | | | | Thanks David Binderma for pointing this out. Note that in practical situations this should not result in any errors due to the position of searches within the ldap_session struct.
* Fix format stringArthur de Jong2014-10-101-3/+3
| | | Thanks Jianhai Luan.
