Likewise Open 5.0.3964 (Default branch)

Likewise Open is an application that joins Linux,Unix, and Mac OS machines to Microsoft ActiveDirectory and securely authenticates users withtheir domain credentials. Features include:joining non-Windows systems to Active Directorydomains in a single step from the command line orfrom a GUI; authenticating users with a singleuser name and password; enforcing the samepassword policies for all platforms; supportingmultiple forests with one-way and two-way crossforest trusts; caching credentials in case yourdomain controller goes down; and providing singlesign-on for SSH and Putty. It does not requireActive Directory schema changes for installation.License: GNU General Public License v2Changes:
Improved performance. When a duplicate UID is found, it will go to AD to get info on a user rather than updating the cache. When a bad username/password is given to domainjoin, it will report "password is incorrect for this account" instead of "call to krb5 failed." Unix attributes from AD are no longer ignored in the default cell.Image

GETPEEREID(3)						   BSD Library Functions Manual 					     GETPEEREID(3)

NAME
getpeereid -- get the effective credentials of a UNIX-domain peer LIBRARY
Utility functions from BSD systems (libbsd, -lbsd) SYNOPSIS
#include <sys/types.h> #include <bsd/unistd.h> int getpeereid(int s, uid_t *euid, gid_t *egid); DESCRIPTION
The getpeereid() function returns the effective user and group IDs of the peer connected to a UNIX-domain socket. The argument s must be a UNIX-domain socket (unix(4)) of type SOCK_STREAM on which either connect(2) or listen(2) have been called. The effective used ID is placed in euid, and the effective group ID in egid. The credentials returned to the listen(2) caller are those of its peer at the time it called connect(2); the credentials returned to the connect(2) caller are those of its peer at the time it called listen(2). This mechanism is reliable; there is no way for either side to influence the credentials returned to its peer except by calling the appropriate system call (i.e., either connect(2) or listen(2)) under different effective credentials. One common use of this routine is for a UNIX-domain server to verify the credentials of its client. Likewise, the client can verify the cre- dentials of the server. IMPLEMENTATION NOTES
On FreeBSD, getpeereid() is implemented in terms of the LOCAL_PEERCRED unix(4) socket option. RETURN VALUES
The getpeereid() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indi- cate the error. ERRORS
The getpeereid() function fails if: [EBADF] The argument s is not a valid descriptor. [ENOTSOCK] The argument s is a file, not a socket. [ENOTCONN] The argument s does not refer to a socket on which connect(2) or listen(2) have been called. [EINVAL] The argument s does not refer to a socket of type SOCK_STREAM, or the kernel returned invalid data. SEE ALSO
connect(2), getpeername(2), getsockname(2), getsockopt(2), listen(2), unix(4) HISTORY
The getpeereid() function appeared in FreeBSD 4.6. BSD
