Dear all
I4m installing a OpenLDAP in one Solaris 9 server. Everything seems to work
ok, but I realized a strange behavior. The slapd daemon initializes too slowly
(approximately 1 minute) and generate this error log:
Feb 23 13:58:41 arrakis slapd[1989]: [ID 702911 local4.debug] @(#) $OpenLDAP:

Feb 23 13:59:41 arrakis slapd[1990]: [ID 100111 local4.debug] slapd starting
The command line is:
/usr/local/libexec/slapd -u ldap -g ldap -h ldaps:/// ldap:///
The user and group 'ldap' are locally stored:
# grep ldap /etc/passwd
ldap:x:30:30:LDAP User:/var/empty:/bin/false
# grep ldap /etc/group
ldap::30:ldap
#
Well, when I initialize the service with the 'root' user (
/usr/local/libexec/slapd -h ldaps:/// ldap:/// ), the problem not occurs, but
it4s not very good.
I tried to change some parameters and has discovered that when I have in
/etc/nsswitch.conf the key 'group:' without the ldap parameter, the
initialization is normal.
That is, the problem isn4t happening when in /etc/nsswitch.conf I have:
Group: files
After the daemon initializes, I can change this line to
Group: files ldap
And everything works very good. But if /etc/nsswich.conf is configured in this
form, occurs the initialization problem.
Has anyone some idea about it?
Thanks in advance
Luiz
