I'm in the process of upgrading Exim from 1.62 to 1.92. I'm also
trying to add a director that uses an LDAP query. My LDAP server
is a umich 3.3 slapd with all of the relevant Critical Angle patches.
When I test my configuration using 'exim -bt <address>', it succeeds
when I run as myself, or when run under xxgdb; but fails when run as
root or as another non-privileged pseudo-user. The failure is:
test@??? cannot be resolved at this time:
virtual_owner director: search_find deferred: ldap_bind_s:
failed to bind the LDAP connection: Can't contact LDAP server
(I've introduced an extra line break after 'ldap_bind_s:' to
improve readability.)
The LDAP server log shows an apparently successful connection.
(I've removed the datestamp and hostname):
slapd[14018]: conn=12 fd=5 connection from unknown (127.0.0.1)
slapd[14018]: conn=12 op=0 BIND dn="" method=128

slapd[14018]: conn=12 op=1 UNBIND
slapd[14018]: conn=12 op=1 fd=5 closed errno=0
The slapd debug log also shows an apparently successful bind:

Particularly puzzling is why it succeeds when run under xxgdb, but
not when run stand-alone.
Any suggestions would be greatly appreciated.
