* KRB5: Offline operation with disabled domainJakub Hrozek2015-09-211-1/+11
| | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/2637 If a subdomain is in the disabled state, switch krb5_child operation into offline mode. Similarly, instead of marking the whole back end as offline, mark just the domain as offline -- depending on the domain type, this would mark the whole back end or just inactivate subdomain.

* Skip CHAUTHTOK_PRELIM when using OTPsJakub Hrozek2014-12-131-3/+35
| | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | The credential cache operations must be now performed by the krb5_child completely, because the sssd_be process might be running as the sssd user who doesn't have access to the ccaches. src/providers/krb5/krb5_ccache.c is still linked against libsss_krb5 until we fix Kerberos ticket renewal as non-root. Also includes a new error code that indicates that the back end should remove the old ccache attribute -- the child can't do that if it's running as the user.

| | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/2271 The current krb5_child code attempts to get a TGT for the convenience of the user using the new password after a password change operation. However, an OTP should never be used twice, which means we can't perform the kinit operation after chpass is finished.

* krb5: save canonical upn to sysdbSumit Bose2013-09-231-2/+3
| | | | | | | | | | | | | If the returned TGT contains a different user principal name (upn) than used in the request, i.e. the upn was canonicalized, we currently save it to sysdb into the same attribute where the upn coming from an LDAP server is stored as well. This means the canonical upn might be overwritten when the user data is re-read from the LDAP server. To avoid this this patch add a new attribute to sysdb where the canonical upn is stored and makes sure it is used when available. Fixes https://fedorahosted.org/sssd/ticket/2060

| | | | | | | | | | | | | | | | | | | | | | | Add a precheck on the actual existence at all of the file/dir ccname targeted (for FILE/DIR types), and bail early if nothing is available. While testing I found out that without this check, the krb5_cc_resolve() function we call as user to check old paths would try to create the directory if it didn't exist. With a ccname of DIR:/tmp/ccdir_1000 saved in the user entry this would cause two undesirable side effects: First it would actually create a directory with the old name, when it should not. Second, because for some reason the umask is set to 0127 in sssd_be, it would create the directory with permission 600 (missing the 'x' traverse bit on the directory. If the new ccache has the same name it would cause the krb5_child process to fal to store the credential cache in it. Related: https://fedorahosted.org/sssd/ticket/2061

* Fix krbcc dir creation issue with MIT krb5 1.11Lukas Slebodnik2013-04-121-1/+11
| | | | | | | | | | | | | | | | In krb5-libs >= 1.11, function krb5_cc_resolve verify if credential cache dir exists. If it doesn't exist, than it will be created with process permissions and not user permissions. Function cc_residual_is_used has already checked for non existing directory, but it wasn't considered to be a failure and therefore next call of krb5_init_context will create directory with wrong permissions. Now if directory doesn't exist, it will be handled like there was not ccache attribute in sysdb cache. We also check if "primary" file in ccache directory has right permissions. But we ignore missing "primary" file. https://fedorahosted.org/sssd/ticket/1822
