2012-08-01Primary server support: support for "disconnecting" connections in LDAPJan Zeleny1-4/+37
This patch adds support for marking existing connections as being disconnected. Each such connection can't be used for new queries and a new one has to be created instead if necessary. This will ensure that pending operations will end gracefully during reconnection. Also all new queries to the server we are reconnecting to will use another (probably newly created) connection.
2012-08-01Primary server support: basic support in failover codeJan Zeleny7-51/+257
Now there are two list of servers for each service. If currently selected server is only backup, then an event will be scheduled which tries to get connection to one of primary servers and if it succeeds, it starts using this server instead of the one which is currently connected to.
2012-08-01Primary server support: introduce concept of reconnectionJan Zeleny2-0/+43
This patch adds two support functions for adding reconnection callbacks and invoking such callbacks. The concept of reconnection is simple: stop using current connection for for new queries to the server without actually going offline.
2012-07-31Unbreak SASLPavel Březina1-9/+12
Patch bc76428246c4ce532abd0eadcd539069fc1d94a8 changed the data type of sasl_minssf from int to ber_len_t. Unfortunately, default value of ldap_sasl_minssf is -1 but ber_len_t is defined as unsigned long. This made SASL mechanism inoperative.
2012-07-31Support fetching of host from sysdb in SELinux codeJan Zeleny1-11/+55
The host record will be fetched if HBAC is used as access provider since the record is already downloaded and it can be trusted to be valid.
2012-07-31Support fetching of HBAC rules from sysdb in SELinux codeJan Zeleny1-14/+47
If HBAC is active, SELinux code will reuse them instead of downloading them from the server again.
2012-07-31Modify hbac_get_cached_rules() so it can be used outside of HBAC codeJan Zeleny2-14/+22
2012-07-30sudo ldap provider: support autoconfiguration of hostnamesPavel Březina1-6/+275
https://fedorahosted.org/sssd/ticket/1420 sudoHost attribute may contain hostname or fqdn of the machine. Sudo itself supports only one hostname and its fqdn - the one that is returned by gethostbyname(). This patch implements autoconfiguration of hostname and fqdn if it has not been set manually by ldap_sudo_hostnames option.
2012-07-27Remove unused member of be_reqJan Zeleny1-3/+0
2012-07-27Move SELinux processing from session to account PAM stackJan Zeleny2-0/+33
The idea is to rename session provider to selinux provider. Processing of SELinux rules has to be performed in account stack in order to ensure that pam_selinux (which is the first module in PAM session stack) will get the correct input from SSSD. Processing of account PAM stack is bound to access provider. That means we need to have two providers executed when SSS_PAM_ACCT_MGMT message is received from PAM responder. Change in data_provider_be.c ensures just that - after access provider finishes its actions, the control is given to selinux provider and only after this provider finishes is the result returned to PAM responder.
2012-07-27Renamed session provider to selinux providerJan Zeleny6-56/+54
2012-07-27Always free request in data provider PAM callbackJan Zeleny1-2/+3
In case of error the request wasn't freed and the callback just ended.
2012-07-25Provide counter of possible matches in SELinux IPA providerJan Zeleny1-6/+6
The counter is important so the for cycle doesn't depend on the first NULL pointer. That would cause potential errors if more records are following after this first NULL pointer.
2012-07-25Fix linking of HBAC rules and SELinux user mapsJan Zeleny1-0/+13
Translate manually memberHost and memberUser to originalMemberUser and originalMemberHost. Without this, the HBAC rule won't be matched against current user and/or host, meaning that no SELinux user map connected to it will be matched againts any user on the system.
2012-07-25Remove ipa_selinux_map_merge()Jan Zeleny3-55/+0
This function is no longer necessary since sysdb interface for copying elements has been implemented.
2012-07-23Added some DEBUG statements into SELinux related codeJan Zeleny1-4/+14
2012-07-23sdap_sudo.c: add missing end of line in few debug messagesPavel Březina1-3/+3
2012-07-18AD: Fix defaults for krb5_canonicalizeStephen Gallagher1-2/+2
The AD provider cannot function with canonicalization because of a bug in Active Directory rendering it unable to complete a password-change while canonicalization is enabled.

2012-07-18IPA: Return and save all SELinux rules in the providerJakub Hrozek1-47/+27
https://fedorahosted.org/sssd/ticket/1421
2012-07-18IPA: Download defaults even if there are no SELinux mappingsJakub Hrozek1-60/+59
We should always download the defaults because even if there are no rules, we might want to use (or update) the defaults.
2012-07-18Modify priority evaluation in SELinux user mapsJan Zeleny1-2/+34
The functionality now is following: When rule is being matched, its priority is determined as a combination of user and host specificity (host taking preference). After the rule is matched in provider, only its host priority is stored in sysdb for later usage. When rules are matched in the responder, their user priority is determined. After that their host priority is retrieved directly from sysdb and sum of both priorities is user to determine whether to use that rule or not. If more rules have the same priority, the order given in IPA config is used. https://fedorahosted.org/sssd/ticket/1360 https://fedorahosted.org/sssd/ticket/1395

2012-07-09heimdal: use sss_krb5_princ_realm to access realmRambaldi1-4/+11
2012-07-06Revert commit 4c157ecedd52602f75574605ef48d0c48e9bfbe8Stef Walter2-36/+0
* This broke corner cases when used with default_tkt_types = des-cbc-crc and DES enabled on an AD domain. * This is fixed in kerberos instead, in a more correct way and in a way which we cannot replicate.
2012-07-06AD: Force case-insensitive operation in AD providerStephen Gallagher1-0/+18
2012-07-06AD: use krb5_keytab for validation and GSSAPIStephen Gallagher3-3/+12
This simplifies configuration by eliminating the need to specifiy both krb5_keytab and ldap_krb5_keytab if the keytab is not located at /etc/krb5.keytab
2012-07-06AD: Add AD access-control providerStephen Gallagher4-1/+188
This patch adds support for checking whether a user is expired or disabled in AD.
2012-07-06AD: Add AD auth and chpass providersStephen Gallagher4-1/+159
These new providers take advantage of existing code for the KRB5 provider, providing sensible defaults for operating against an Active Directory 2008 R2 or later server.
2012-07-06AD: Add AD identity providerStephen Gallagher6-0/+1165
This new identity provider takes advantage of existing code for the LDAP provider, but provides sensible defaults for operating against an Active Directory 2008 R2 or later server.
2012-07-06LDAP: Rename user and group maps for ADStephen Gallagher2-4/+4
This will eliminate ambiguity for the AD provider
2012-07-06KRB5: Create a common init routine for krb5_child optionsStephen Gallagher4-98/+135
This will reduce code duplication between the krb5, ipa and ad providers
2012-07-06KRB5: Drop memctx parameter of krb5_try_kdcipStephen Gallagher4-15/+17
This function is not supposed to return any newly-allocated memory directly. It was actually leaking the memory for krb5_servers if krb5_kdcip was being used, though it was undetectable because it was allocated on the provided memctx. This patch removes the memctx parameter and allocates krb5_servers temporarily on NULL and ensures that it is freed on all exit conditions. It is not necessary to retain this memory, as dp_opt_set_string() performs a talloc_strdup onto the appropriate context internally. It also updates the DEBUG messages for this function to the appropriate new macro levels.
2012-07-06KRB5: Some logging enhancements for krb5_childStephen Gallagher1-6/+13
2012-07-06Fix crash when interface doesn't have an addressStef Walter1-0/+3
* This is similar to the code in ipa_dyndns_update_send()
2012-07-02LDAP: Print extended failure message for SASL bindStephen Gallagher1-2/+14
2012-07-02IPA: Don't hang onto memory longer than necessaryStephen Gallagher1-0/+1
This request and attached memory would be freed at the end of access-check processing, but it's a waste to keep it around.
2012-06-30Fix segfault when sudo is not configured.Simo Sorce1-1/+2
Sudo support is optional, when it is not configured sudorules_map is not initialized and dereferencing it will cause a segmentation fault.
2012-06-29KRB5: Initialize the credential cache type properlyStephen Gallagher1-0/+11
We weren't guaranteeing that the cctype-specific callbacks were initialized before using them. This bug only presented itself for users who were logging in without a ccacheFile attribute in the LDB (for example, first-time logins).
2012-06-29sudo ldap provider: support autoconfiguration of IP addressesPavel Březina1-1/+179
sudoHost attribute may contain IPv4 or IPv6 host/network address. This patch adds support for autoconfiguration of these information.
2012-06-29sudo ldap provider: do per-host updatesPavel Březina1-3/+160
Add host information to LDAP filters.
