Hello,

Compiling this package against libressl instead of openssl causes a stack
overflow in nslcd when an authentication attempt comes in.

>From messages:

Dec  7 16:21:06 <server> nslcd: stack overflow detected; terminated
Dec  7 16:21:06 <server> kernel: <118>Dec  7 16:21:06 <server> nslcd: stack
overflow detected; terminated

The exact same configuration compiled against openssl works just fine.

The nslcd.conf file:

pagesize 1000
referrals off
filter shadow
(&(objectClass=posixAccount)(!(objectClass=computer))(uidNumber=*))
map shadow shadowLastChange  pwdLastSet
uid nslcd
gid nslcd
uri ldap://<ldapserver>:389
base dc=domain,dc=tld
ssl starttls
tls_cacertdir /usr/local/etc/openldap/certs
binddn cn=bindacct,dc=domain,dc=tld
bindpw bindpassword
