* slapi-nis: don't search in SSSD when memberUid has no '@' separatorAlexander Bokovoy2015-07-281-2/+5
| | | | | | | | | | | | | In the case there are no groups in cn=groups map that have certain memberUid as a member, we look at possibility that this user might be coming from a trusted AD forest. However, all users from trusted AD forests do have '@' separator in the name between the user name and the domain. In case there is no '@' separator, consider such search as not valid for lookups in SSSD. Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1243823
* Make sure default buffer for nsswitch operations is big enoughAlexander Bokovoy2015-03-261-4/+1
| | | | | | By default initial buffer sizes for getgrent/getgrnam/... functions are way small for large groups in Active Directory so make sure we have something reasonable for groups with hundreds or thousands members.
* nss: make sure to remember the length of reallocated bufferAlexander Bokovoy2015-03-261-0/+4

* schema-compat: use libnss_sss.so.2 explicitly to resolve trusted domain ↵Alexander Bokovoy2015-03-264-35/+220
| | | | | | | | | | | | users via NSS When Schema Compatibility plugin is configured to enumerate users and groups from Active Directory domains trusted by FreeIPA, use nss_sss module directly instead of following nsswitch.conf configuration. The issue with nsswitch.conf configuration is in the fact that for each request all modules in NSS chain are processed while only one of them is responsible for users from trusted Active Directory domains, namely, nss_sss.
* Use slapi_entry_find_attr instead of slapi_entry_attr_existsAlexander Bokovoy2015-03-262-2/+8
| | | | | | To keep slapi-nis code portable to older versions of 389-ds-base, avoid using slapi_entry_attr_exists() as it was only introduced in 389-ds-base 1.3.3.0.
* schema-compat: support ID overrides in bind callbackAlexander Bokovoy2014-10-303-36/+111
| | | | | | | | If RDN of the bind DN is overridden within the ID view, rewrite the target to use original value of the uid attribute. If original uid attribute is not available, fail the search and thus the whole bind request by claiming that bind DN does not exist.
* ID views: ignore searches for views outside the subtrees of schema-compat setsAlexander Bokovoy2014-10-302-11/+81
| | | | | | | | | | | | | | | | | | | | schema-compat plugin may provide multiple disjoint subtrees which can be used to request overridden entries by prefixing the subtree suffix with a cn=<name of view>,cn=views,<subtree suffix> As subtrees may be disjoint, we cannot rely on the common suffix. Thus, any attempt to replace target DN and update filter terms must only be done once we are sure the search will be done in the subtree. This optimization prevents mistakenly changing the search filter when FreeIPA and SSSD search for the ID overrides themselves, as the same structure of the target DN is used for cn=views,cn=accounts,$SUFFIX subtree in FreeIPA. This subtree is never handled by slapi-nis and should be ignored. https://bugzilla.redhat.com/show_bug.cgi?id=1157989
* slapi-nis: normalize memberUid search filter when searching AD usersAlexander Bokovoy2014-10-101-3/+32
| | | | | | | | | | | | | | | | memberUid attribute uses IA5 String comparison which is case-sensitive. At the same time, uid attribute uses case-insensitive comparison. When memberUid is constructed for groups from AD, SSSD normalizes names to a lower case. slapi-nis records these entries as they produced by SSSD. However, the search filter is not modified, thus case-sensitive comparison of memberUid attribute may fail match of the original term. Workaround the issue by low-casing memberUid term in the search filter if it includes '@' sign, meaning we are searching on fully-qualified user name provided by SSSD. https://bugzilla.redhat.com/show_bug.cgi?id=1130131
* Add support for FreeIPA ID viewsAlexander Bokovoy2014-10-105-31/+585
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FreeIPA ID views allow to override POSIX attributes for certain users and groups. A support is added to allow using specific ID view when serving compatibility tree. Each user or group entry which has an override in the view is amended with the overridden values from the view before served out to the LDAP client. A view to use is specified as a part of base DN: cn=<view>,cn=views,cn=compat,$SUFFIX where cn=compat,$SUFFIX is the original compatibility tree base DN. Each entry, when served through the view, gets new DN rewritten to specify the view. Additionally, if override in the view changes uid (for users) or cn (for groups) attribute, the entry's RDN is changed accordingly. For groups memberUid attribute is modified as well in case there is an override in the view that changes uid value of that member. FreeIPA ID views support overrides for users of trusted Active Directory domains. In case of a trusted AD domain's user or group is returned via compatibility tree, view overrides are applied in two stages: 1. SSSD applies default view for AD users 2. slapi-nis applies explicitly specified (host-specific) view on top of the entry returned by SSSD Thus, slapi-nis does not need to apply default view for AD users and if there are no host-specific views in use, there is no need to specify a view in the base DN, making overhead of a default view for AD users lower.
* Correct the NIS defaults for "hosts" mapsNalin Dahyabhai2014-04-221-4/+4
| | | | | The values for NIS hosts.byname and hosts.byaddr maps should start with addresses, not names. Reported by Rik Megens.
* Better handle out-of-memory reading configurationNalin Dahyabhai2014-03-171-8/+6
| | | | | Avoid calling strdup() in a situation where we don't need to, so that we can better handle cases where it fails (static analysis).
* Accept schema-compat-lookup-nsswitch: passwdNalin Dahyabhai2014-03-171-1/+8
| | | | | | Treat "schema-compat-lookup-nsswitch: passwd" in the configuration the same as "schema-compat-lookup-nsswitch: user", to not fail for people who forget and try to use the nsswitch database name.
* Better handle out-of-memory reading configurationNalin Dahyabhai2014-03-171-4/+20
| | | | | | | If we hit out-of-memory (strdup() failures) while reading the configuration, don't crash (static analysis). In some cases, this means we proceed with garbage data until the copy_config() function sanity-checks its input and output.
* Better handle out-of-memory reading configurationNalin Dahyabhai2014-03-171-2/+15
| | | | | If we hit out-of-memory (strdup() failures) while reading the configuration, don't crash (static analysis).

* Coverity#11937: use proper structure to pass to map_data_set_entry()Alexander Bokovoy2013-11-151-6/+8
| | | | | map_data_set_entry() passes pointers to the lengths of the key and the value to map_data_save_list() which interpretes them as arrays of integers.
* Try reconnecting if rpcbind EPIPEs usNalin Dahyabhai2013-10-013-60/+94
| | | | | | | If the NIS server encounters an EPIPE while attempting to communicate with the portmapper, try to reconnect before giving up on registering. Depending on which RPC implementation is used, rpcbind may drop idle clients after 30 seconds, and our startup can take longer than that.
* Use MSG_NOSIGNAL when sending a request to portmapNalin Dahyabhai2013-10-011-1/+1

* Up the log severity on portmap errorsNalin Dahyabhai2013-10-011-9/+9
| | | | | | Log errors encountered while talking to portmap/rpcbind at level SLAPI_LOG_FATAL rather than at the previous SLAPI_LOG_PLUGIN, so that they show up even when we're not actively debugging.
* Add ignore-subtree and restrict-subtree settingsNalin Dahyabhai2013-09-197-74/+333
| | | | | | | | | | | | | | Add {nis,schema-compat}-ignore-subtree (subtrees under which we ignore contents and updates )and {nis,schema-compat}-restrict-subtree (subtrees out of which we ignore contents and updates, if set) settings, and default the former to "cn=tasks,cn=config". This should avoid cases where we're looking through the ldbm backend for entries which have a dangling reference to a newly-added task (which, because it's in the DSE, means we acquire an ldbm lock after acquiring our internal lock) while also updating a compat entry after its source entry is modified (for example, by the memberOf plugin, which results in us attempting to acquire our lock while the ldbm lock is already held).

* Add schema-compat-relevant-subtreeNalin Dahyabhai2013-09-124-3/+42
| | | | | | | | | | Add a schema-compat-relevant-subtree configuration option, listing the only parts of the DIT that we should ever look at, either as source entries or as other entries which contain data which might be pulled in as part of computing the contents of compat entries. This is more or less the whitelist to schema-compat-ignore-subtree's blacklist.
* Add schema-compat-ignore-subtreeNalin Dahyabhai2013-09-125-1/+115
| | | | | | | Add a schema-compat-ignore-subtree configuration option, listing parts of the DIT that we should never look at, neither as source entries nor as random other entries which contain data which might be pulled in as part of computing the contents of compat entries.
