I think this should be ``slapd_db_recover -h $PWD''
The fact that it's saying that it is skipping read-only either means that
the /ver/lib/ldap directory is on a read-only file system, or perhaps
slapd_db_recover requires the ``-h'' option to really do it's work.
I think that slapd_db_recover is a version of the Sleepycat Berkeley
database (bdb) db_recover routine, specific to the version of bdb on which
openldap-server is built. The bdb is some of the worst looking spaghetti
code I have seen in over 40 years of programming work (look at the #if
statements in the perl or python bdb routines to get an idea of how ugly it
is with dependencies on both major and minor releases).
As a last resort, ``rm /var/lib/ldap/*'' will clear all the openldap data
files allowing it to restart so you can rebuild its data from scratch.
