Skip CHAUTHTOK_PRELIM when using OTPs https://fedorahosted.org/sssd/ticket/2484 When OTPs are used, we can only used each authtoken at most once. When it comes to Kerberos password changes, this was only working previously by accident, because the old authtoken was first used to verify the old password is valid and not expired and then also to acquire a chpass principal. This patch looks at the user object in LDAP to check if the user has any OTPs enabled. If he does, the CHAUTHTOK_PRELIM step is skipped completely so that the OTP can be used to acquire the chpass ticket later. Reviewed-by: Sumit Bose <sbose@redhat.com>

When set, the option contains a list of LDAP attributes the LDAP provider would download and store in addition to the usual set. The list can either contain LDAP attribute names only, or colon-separated tuples of LDAP attribute and SSSD cache attribute name. In case only LDAP attribute name is specified, the attribute is saved to the cache verbatim. Using a custom SSSD attribute name might be required by environments that configure several SSSD domains with different LDAP schemas.

LDAP: Detect the presence of POSIX attributes When the schema is set to AD and ID mapping is not used, there is a one-time check ran when searching for users to detect the presence of POSIX attributes in LDAP. If this check fails, the search fails as if no entry was found and returns a special error code. The sdap_server_opts structure is filled every time a client connects to a server so the posix check boolean is reset to false again on connecting to the server. It might be better to move the check to where the rootDSE is retrieved, but the check depends on several features that are not known to the code that retrieves the rootDSE (or the connection code for example) such as what the attribute mappings are or the authentication method that should be used.

AD: filter domain local groups for trusted/sub domains In Active Directory groups with a domain local scope should only be used inside of the specific domain. Since SSSD read the group memberships from LDAP server of the user's domain the domain local groups are included in the LDAP result. Those groups should be filtered out if the domain is a sub/trusted domain, i.e. is not the domain the client running SSSD is joined to. The groups will still be in the cache but marked as non-POSIX groups and no GID will be assigned. Fixes https://fedorahosted.org/sssd/ticket/2178

Add new option ldap_group_type

AD: use LDAP for group lookups The group memberships cannot be reliable retrieved from the Global Catalog. By default the memberOf attribute is not replicated to the GC at all and the member attribute is copied from the local LDAP instance to the GC running on the same host, but is only replicated to other GC instances for groups with universal scope. Additionally the tokenGroups attribute contains invalid SIDs when used with the GC for users from a different domains than the GC belongs to. As a result the requests which tries to resolve group-memberships of a AD user have to go to a LDAP server from the domain of the user.

LDAP: Make the cleanup task reusable for subdomains Instead of always performing the cleanup on the main domain, the task now accepts a sdap_domain structure to perform the cleanup on. This change will make the cleanup task reusable for subdomains.

LDAP: Convert enumeration to the ptask API https://fedorahosted.org/sssd/ticket/1942 Identity providers other than LDAP need to customize the enumeration in different ways while sharing the way the task is scheduled etc. The easiest way to accomplish it is to leverage the recently introduced ptask framework.

LDAP: Move the ldap enum request to its own reusable module The LDAP enumeration was too closely tied to the LDAP identity provider. Because some providers might need special handling such as refresh the master domain record before proceeding with the enumeration itself, this patch splits the request itself to a separate async request and lets the ldap_id_enum.c module only configure this new request. Also move the enum timestamp to sdap_domain to make the enum tracking per sdap domain. The cleanup timestamp will be moved in another patch.

LDAP: Use domain-specific name where appropriate The subdomain users user FQDN in their name attribute. However, handling of whether to use FQDN in the LDAP code was not really good. This patch introduces a utility function and converts code that was relying on user/group names matching to this utility function. This is a temporary fix until we can refactor the sysdb API in #2011.

LDAP: Add utility function sdap_copy_map The AD subdomains will only use default options values. This patch introduces a new utility function sdap_copy_map() that copies the default options map. Subtask of: https://fedorahosted.org/sssd/ticket/1962

Add now options ldap_min_id and ldap_max_id Currently the range for Posix IDs stored in an LDAP server is unbound. This might lead to conflicts in a setup with AD and trusts when the configured domain uses IDs from LDAP. With the two noe options this conflict can be avoided.

A new option krb5_use_kdcinfo https://fedorahosted.org/sssd/ticket/1883 The patch introduces a new Kerberos provider option called krb5_use_kdcinfo. The option is true by default in all providers. When set to false, the SSSD will not create krb5 info files that the locator plugin consumes and the user would have to set up the Kerberos options manually in krb5.conf

LDAP: new SDAP domain structure Previously an sdap_id_ctx was always tied to one domain with a single set of search bases. But with the introduction of Global Catalog lookups, primary domain and subdomains might have different search bases. This patch introduces a new structure sdap_domain that contains an sssd domain or subdomain and a set of search bases. With this patch, there is only one sdap_domain that describes the primary domain.

Adding option to disable retrieving large AD groups. This commit adds new option ldap_disable_range_retrieval with default value FALSE.

Adds 3 new error codes: ERR_CHPASS_DENIED - Used when password constraints deny password changes ERR_ACCOUNT_EXPIRED - Account is expired ERR_PASSWORD_EXPIRED - Password is expired

AD: replace GID/UID, do not add another one The code would call sysdb_attrs_add_uint32 which added another UID or GID to the ID=0 we already downloaded from LDAP (0 is the default value) when ID-mapping an entry. This led to funky behaviour later on when we wanted to process the ID.

Improvements for LDAP Password Policy support Display warnings about remaining grace logins and password expiration to the user, when LDAP Password Policies are used. Improved detection if LDAP Password policies are supported by LDAP Server.

Better cleanup task handling Implements a different mechanism for cleanup task. Instead of just deleting expired entries, this patch adds a new option account_cache_expiration for domains. If an entry is expired and the last login was more days in the past that account_cache_expiration, the entry is deleted. Groups are deleted if they are expired and and no user references them (no user has memberof: attribute pointing at that group). The parameter account_cache_expiration is not LDAP-specific, so that other future backends might use the same timeout setting. Fixes: #391
