| Doc Text: |
- OpenLDAP server enabled on ldaps port (636)
- slapd might not manage to bind to ldaps port, because this port can be already taken by other process using bindresvport() glibc call
- added configuration file for portreserve service to reserver ldaps port, updated slapd initscript to remove the reservation before starting slapd service
- ldaps port is available for slapd service and cannot be taken by bindresvport() glibc call

What ports are we talking about? Ports to which openldap server connect to answer client its queries? (In reply to comment #5) > What ports are we talking about? Ports to which openldap server connect to > answer client its queries? About the server ports clients connect to. In this case 389/tcp+udp and 636/tcp+udp. And 636 is in within the range.

To avoid port conflicts with services such as CUPS or IMAP openldap should be using portreserve for reserving respective ports within range 600 - 1023. According to /etc/services openldap might be using port(s) withing this range. Typical changes required: Given a SysV service package that uses a particular port, (say, krb5_prop/tcp - 754): 1) Create a file named after the service, for example 'krb5_prop', which contains: krb5_prop/tcp 2) In the spec, install this file in /etc/portreserve, i.e., /etc/portreserve/krb5_prop 3) In the spec, add 'Requires: portreserve' to the package that provides the server. 4) In the init script, in the start() stanza, add: [ -x /sbin/portrelease ] && /sbin/portrelease krb5_prop &>/dev/null || : before starting the daemon. Some background can be found in bug 103401.
