LFC_GETIDMAP(3) 					       LFC Library Functions						   LFC_GETIDMAP(3)

NAME

       lfc_getidmap - get virtual uid/gid(s) associated with a given dn/role(s)

SYNOPSIS

       #include <sys/types.h>
       #include "lfc_api.h"

       int lfc_getidmap (const char *username, int nbgroups, const char **groupnames, uid_t *userid, gid_t *gids)

       int lfc_getidmapc (const char *username, const char *user_ca, int nbgroups, const char **groupnames, uid_t *userid, gid_t *gids)

DESCRIPTION

       lfc_getidmap gets the virtual uid/gid(s) associated with a given dn/role(s).  If the dn or any of the roles does not exist yet in the Data-
       base an entry is added to the mapping table.

       username
	      specifies the user name (dn).  It must be at most 255 characters long.

       user_ca
	      specifies the CA from the user proxy.  It must be at most 255 characters long.

       nbgroups
	      is the number of group names.

       groupnames
	      is the address of an array of group names (vo/role).  Each group name must be at most 255 characters  long.   This  pointer  can	be
	      NULL.  In this case the vo is obtained from a static mapping file.

       userid specifies the address of a buffer to receive the Virtual User Id.

       gids   specifies  the  address  of  a buffer to receive the Virtual Group Ids.  It must be big enough to receive nbgroups group ids, but at
	      least one group id in case nbgroups is zero.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       ENOMEM	    Memory could not be allocated in the server to receive the group names or to send back the gids.

       EACCES	    One of username, user_ca or the primary (first) group is banned.

       EFAULT	    username, userid or gids is a NULL pointer.

       EINVAL	    nbgroups is negative or the length of username, user_ca or of one of the group names exceeds 255.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       SENOMAPFND   DISABLEAUTOVIDS is set and username or one of the groups does not exist.

       ENSNACT	    Name server is not running or is being shutdown.

LFC_CHOWN(3)						       LFC Library Functions						      LFC_CHOWN(3)

NAME

       lfc_chown - change owner and group of a LFC directory/file in the name server

SYNOPSIS

       #include <sys/types.h>
       #include "lfc_api.h"

       int lfc_chown (const char *path, uid_t new_uid, gid_t new_gid)

       int lfc_lchown (const char *path, uid_t new_uid, gid_t new_gid)

DESCRIPTION

       lfc_chown  sets	the  owner and the group of a LFC directory/file in the name server to the numeric values in owner and group respectively.
       If owner or group is specified as -1, lfc_chown() does not change the corresponding ID of the file.

       lfc_lchown is identical to lfc_chown except for symbolic links: it does not follow the link but changes the ownership of the link itself.

       path   specifies the logical pathname relative to the current LFC directory or the full LFC pathname.

       To change the owner ID, if the group ID does not change and if the caller and the new owner ID belong to that group, GRP_ADMIN privilege is
       needed,	otherwise the caller must have ADMIN privilege in the Cupv database.  To change the group ID, the effective user ID of the process
       must match the owner ID of the file and the new group must be in the list of groups the caller belong to or  the  caller  must  have  ADMIN
       privilege in the Cupv database.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       EPERM	    The effective user ID does not match the owner of the file and the caller does not have ADMIN privilege in the Cupv database.

       ENOENT	    The named file/directory does not exist or is a null pathname.

       EACCES	    Search permission is denied on a component of the path prefix.

       EFAULT	    path is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       EINVAL	    new_uid or new_gid is invalid.

       ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.
