dbm-auth-file: Berkeley DB (Hash, version 9, native byte-order)and then I loaded the module and configured it in a <Directory> as follows,AuthType BasicAuthName DocumentsAuthBasicProvider dbmAuthDBMType DBAuthDBMUserFile "/home/tixu/httpd-2.4.20-bin/dbm-auth-file"and then I got the "DSO load failed" message:[Thu May 05 18:12:29.915467 2016] [authn_dbm:error] [pid 9107:tid 140031532377856] (20019)DSO load failed: [client 127.0.0.1:54442] AH01754: could not open dbm (type DB) auth file: /home/tixu/httpd-2.4.20-bin/dbm-auth-fileI changed the AuthBasicProvider to be "default" and used "htdbm" to create the DBM files (in which can it generates a .dir and .pag file). And the module goes correctly.Thus, I'm sure there it the problem of the "AuthDBMType". But I'm not sure if this is a bug in the implementation of mod_authn_dbm or a problem of some native libs in my system or some incompatibility caused by the dbmmanger?mod_authn_dbm calls APR to open the DBM file, definitely supporting Berkeley DB but with the note "not all may be available at run time":https://apr.apache.org/docs/apr/2.0/group___a_p_r___util___d_b_m.html#gaf7295ba8157f487b78319e168e1344b4From what I can see, the error comes all the way from the function dbm_open_type or in APR (apr_dbm.c).It might be a problem of the httpd/apr version that you are using and/or related configure flags needed. Could you please give us more details? After this issue is resolved I'll update the documentation with more details!
