Just doing a little follow up here, I think I tracked my issues down. I am
not going to get into too much detail about how I eventually figured this
out but.
If I apt-get source sendmail (8.12.6), comment out the following in the
libsm/ldap.c:
# ifdef LDAP_OPT_RESTART
ldap_set_option(ld, LDAP_OPT_RESTART, LDAP_OPT_ON);
# endif /* LDAP_OPT_RESTART */
Then rebuild the package, everything works fine.
I discoivered this after updating a prodocution box that was running ldap
maps in sendmail to sendmail_8.12.6-6Woody and sicovering sendmail was
giving off the same errors as pam_ldap when invoked from sendmail (Can not
connect to server). I quick downgraded and went the hunt. 8.12.6 is when
sendmail started using LDAP_OPT_RESTART so I took a wild guess went the
comment and this seemed to fix things up for me.
Hopefully someone elsewho has the same problem will see this post.
Cheers,
Stewart
