5137 | * with -lsecurity or some such. | |
5138 | * This interface is used at least by Solaris, HP-UX, IRIX, and Linux. | |
5139 | * (and SCO?) | |
5140 | * | |
5141 | * AIX getpwnam() is clever enough to return the encrypted password | |
5142 | * only if the caller (euid?) is root. | |
5143 | * | |
e549f1c5 | 5144 | * There are at least three other shadow password APIs. Many platforms |
bcf53261 JH |
5145 | * seem to contain more than one interface for accessing the shadow |
5146 | * password databases, possibly for compatibility reasons. | |
3813c136 | 5147 | * The getsp*() is by far he simplest one, the other two interfaces |
bcf53261 JH |

3813c136 | 5172 | * Mention I_PROT here so that Configure probes for it. |
bcf53261 JH |
5173 | * |
5174 | * In HP-UX for getprpw*() the manual page claims that one should include | |
5175 | * <hpsecurity.h> instead of <sys/security.h>, but that is not needed | |
5176 | * if one includes <shadow.h> as that includes <hpsecurity.h>, | |
5177 | * and pp_sys.c already includes <shadow.h> if there is such. | |
3813c136 JH |
5178 | * |
5179 | * Note that <sys/security.h> is already probed for, but currently | |
5180 | * it is only included in special cases. | |
301e8125 | 5181 | * |
bcf53261 JH |
5182 | * In Digital UNIX/Tru64 if using the getespw*() (which seems to be |
5183 | * be preferred interface, even though also the getprpw*() interface | |
5184 | * is available) one needs to link with -lsecurity -ldb -laud -lm. | |
3813c136 JH |
5185 | * One also needs to call set_auth_parameters() in main() before |
5186 | * doing anything else, whether one is using getespw*() or getprpw*(). | |
