The ldapsearch command can simply be used as ldapsearch -x to see everything in the database. The -x means to use simple authentication instead of SASL authentication. When this command is used though, user passwords (even encrypted ones) will not be shown in the output. To see the userpassword field, use:
ldapsearch -x -D “cn=Manager,dc=gray,dc=uchicago,dc=edu” -W
and enter the password.
