According to the source code for ldconfig (/usr/src/sbin/ldconfig/ldconfig.c), ldconfig requires that the library file have a name that: * begins with 'lib' * contains '.so.' (note the trailing period) This is in the dodir() function, around line 270. It does not seem to require a number after the final dot, though, based on a cursory reading of the source. So, 'pam_XXX.so' isn't in the hints file because it's not a 'libXXX', and the others don't have a trailing version number.
