I am having problems with mysql authentication using courier-authlib (authdaemond). This is getting really frustrating. The error I am getting is:

Aug 28 17:48:48 www authdaemond: modules="authmysql", daemons=5
Aug 28 17:48:48 www authdaemond: Installing libauthmysql
Aug 28 17:48:48 www authdaemond: libauthmysql.so: cannot open shared object file: No such file or directory

I then did a ldd on /usr/lib/courier-authlib/libauthmysql.so.0 (this is the only libauthmysql.so.0 on the system).

It gave me the error that libmysqlclient.so.14 and libcourierauthcommon.so.0 could not be found. I searched the filesystem for these libraries and found them. I did an ldd on each of them and they loaded correctly. I also made sure that these libraries are on the ld.so.config as well as checking to make sure they are listed on a ldconfig -v.

It appears that the libraries are there and will load properly, but -- for some reason -- the library libauthmysql.so.0 can not find them. This is really weird -- they are listed in the ld cache (as shown by the ldconfig -v) but the library libauthmysql.so.0 does not see them.....

Any ideas?
