I have freshly built an
OpenLDAP-2.1.5/BDB-4.1.24/cyrus-sasl-2.1.7/OpenSSL-0.9.7-dev
system on Solaris-8. If I run 'ldappasswd -x -W -S -D <dn1> <dn2>' the command
hangs
and the server is in a deadlock situation. Please find below a stacktrace of all

threads and the last part of fulltrace output and a truss output.

Is it possible that I have built the system wrong?

here are my configure statements I used:

OpenLDAP: 	./configure --prefix=/opt/openldap
--sysconfdir=/var/spool/openldap/etc \
		--datadir='$$(prefix)/lib' --enable-crypt --without-kerberos \
		--enable-ldap --enable-dynamic --enable-modules --with-tls --with-cyrus-sasl

SASL:           ./configure --prefix=/opt/openldap \
		--with-des=$(spool_builddir) --disable-gssapi --disable-krb4 \
		--with-staticsasl --enable-static --disable-shared --with-dblib=none

BDB:            ../dist/configure --prefix=/opt/openldap --disable-shared

thanks for any help

with best regards
