5063 | * We currently support only the SysV getsp* shadow password interface. |
5064 | * The interface is declared in <shadow.h> and often one needs to link | |
5065 | * with -lsecurity or some such. | |
5066 | * This interface is used at least by Solaris, HP-UX, IRIX, and Linux. | |
5067 | * (and SCO?) | |
5068 | * | |
5069 | * AIX getpwnam() is clever enough to return the encrypted password | |
5070 | * only if the caller (euid?) is root. | |
5071 | * | |
e549f1c5 | 5072 | * There are at least three other shadow password APIs. Many platforms |
bcf53261 JH |
5073 | * seem to contain more than one interface for accessing the shadow |
5074 | * password databases, possibly for compatibility reasons. | |
3813c136 | 5075 | * The getsp*() is by far he simplest one, the other two interfaces |
bcf53261 JH |
5076 | * are much more complicated, but also very similar to each other. |

5101 | * |
5102 | * In HP-UX for getprpw*() the manual page claims that one should include | |
5103 | * <hpsecurity.h> instead of <sys/security.h>, but that is not needed | |
5104 | * if one includes <shadow.h> as that includes <hpsecurity.h>, | |
5105 | * and pp_sys.c already includes <shadow.h> if there is such. | |
3813c136 JH |
5106 | * |
5107 | * Note that <sys/security.h> is already probed for, but currently | |
5108 | * it is only included in special cases. | |
301e8125 | 5109 | * |
bcf53261 JH |
5110 | * In Digital UNIX/Tru64 if using the getespw*() (which seems to be |
5111 | * be preferred interface, even though also the getprpw*() interface | |
5112 | * is available) one needs to link with -lsecurity -ldb -laud -lm. | |
3813c136 JH |
5113 | * One also needs to call set_auth_parameters() in main() before |
5114 | * doing anything else, whether one is using getespw*() or getprpw*(). | |
5115 | * | |
5116 | * Note that accessing the shadow databases can be magnitudes | |
5117 | * slower than accessing the standard databases. | |
